On Monday, at 10.14 pm UTC, the Wikimedia server cluster experienced a total power failure, taking down Wikipedia, Wikinews, and all other Wikimedia websites.

The servers are housed in a colocation facility (colo) in Tampa, Florida, USA. They occupy two racks, with each rack receiving electricity from two independent supplies. However, both supplies have circuit-breakers in them, and both opened at the same time, leading to a total power failure. All computers immediately went down. It’s normal for fire safety regulations to prohibit uninterruptible power supplies in colos, with the colo providing its own UPS and generator instead. The circuit breakers were on the computer side of this emergency power system, so none of the computers continued to receive power to survive the breaker trip or shut down safely.

The actual reason why the circuit breakers tripped is currently unknown.

When power was restored, it was discovered that most of the MySQL databases that store the data which makes up Wikipedia et al had been corrupted. The main database and the four slaves had all damaged the data on their hard disk drives beyond the ability of the auto-correction to repair. Only one copy survived safely, on a machine that is used for report generation and maintenance tasks, which remained 31 hours backlogged while catching up after an unusually heavy update load during the previous week.

Volunteer Wikimedia engineers worked through the night rebuilding the databases from the sole good copy onto the other servers. The Wikipedia database is over 180Gb in size, making the copying process last 1.5 – 2 hours for every server it was performed upon.

Regular back-ups of the database of Wikipedia projects are maintained – the encyclopedia in its entirety was not at risk. The last database download was made on February 9; all edits since then could only have been laboriously rebuilt from logs and recovered from the damaged database requiring much more time and effort.

Limited read-only service was established late Tuesday afternoon, with editing becoming possible 24 hours after the power failure. Final repairs continue now, as well as upgrades to prevent similar issues in the future. Server-intensive features, such as categories and ‘watchlists’ that display recent changes to selected articles to registered users, remain disabled to ease the load on the recovering systems.

The process which led to the damage originated with the operating system, disk controllers, or hard drives failing to flush the data correctly.

If the power to a database server is cut mid-write, the database may be corrupted and unreadable, however the operating system, hardware, and software are designed to make this very unlikely. In a previous incident in 2004 power was also lost to a server but the database was undamaged.

To avoid such damage, each database server saves a copy of an edit to be applied to the database on a separate storage system before making the actual update to the database itself. This so-called ‘write-ahead logging’ should ensure that in the event of a system crash, the database can be rebuilt from a ‘last-good’ state by replaying the edits saved in the log.

Earlier this year popular blogging site LiveJournal suffered a similar power failure when another customer at their colocation facility pressed an Emergency Power Off button, intended for use only by firefighters. The company suffered database corruption similar to that seen at Wikimedia.

LiveJournal are now fitting UPS to their servers to ensure that they have time to shut down safely in the event of a power failure. Wikimedia was said to be investigating the possibility of fitting similar equipment at the time of this failure.

Several pundits have suggested that the use of another database, such as the proprietary database Oracle or the free PostgreSQL, would have avoided the database corruption seen at the server cluster. A post-mortem of the incident show the failure was in the operating system, or the hardware, or some combination of the two. LiveJournal, which also uses MySQL, reported similar database corruption after their power cut.

The Wikimedia foundation only allows the use of free software on its systems, and future versions of the Mediawiki software will support the PostgreSQL database.

Users are reminded that during times of system failure or excessive demand, they can still search Wikipedia using Google. The articles may be viewed using Google’s cache.

On Sunday, Wikinews interviewed creator of memorial site LisaMcPherson.org, former Lisa McPherson Trust employee and long time Scientology critic Jeff Jacobsen.

LisaMcPherson.org is a memorial site created in 1997 containing information on her death and the resulting legal case against the Church of Scientology.

Lisa McPherson died in 1995 while in the care of the Church of Scientology. After a car accident, she became mentally unstable. Scientologists removed her from the hospital and placed her in the Introspection Rundown, she died 17 days later while still in care of the Church. She was used as an icon during Project Chanology, the protest of the Church of Scientology by Anonymous. Protesters were pictured with signs that said “Remember Lisa McPherson” and “Ask Scientology Why Lisa McPherson Died”, other protesters had posters with her picture on it.

Controversy has arisen over the reported presence of blue asbestos on the MV Freewinds, a cruise ship owned by the Church of Scientology. According to the Saint Martin newspaper The Daily Herald and the shipping news journal Lloyd’s List, the Freewinds was sealed in April and local public health officials on the Caribbean island of Curaçao where the ship is docked began an investigation into the presence of asbestos dust on the ship. Former Scientologist Lawrence Woodcraft supervised work on the ship in 1987, and attested to the presence of blue asbestos on the Freewinds in an affidavit posted to the Internet in 2001. Woodcraft, a licensed architect by profession, gave a statement to Wikinews and commented on the recent events.

According to The Daily Herald, the Freewinds was in the process of being renovated by the Curaçao Drydock Company. The article states that samples taken from paneling in the ship were sent to the Netherlands, where an analysis revealed that they “contained significant levels of blue asbestos”. An employee of the Curaçao Drydock Company told Radar Online in an April 30 article that the Freewinds has been docked and sealed, and confirmed that an article about asbestos ran in the local paper.

Lloyd’s List reported that work on the interior of the Freewinds was suspended on April 27 after health inspectors found traces of blue asbestos on the ship. According to Lloyd’s List, Frank Esser, Curaçao Drydock Company’s interim director, joined Curaçao’s head of the department of labor affairs Christiene van der Biezen along with the head of the local health department Tico Ras and two inspectors in an April 25 inspection of the ship. “We are sending someone so that they can tell us what happened, where it came from, since when it has been there,” said Panama Maritime Authority’s director of merchant marine Alfonso Castillero in a statement to Lloyd’s List.

The Church of Scientology purchased the ship, then known as the Bohème, in 1987, through an organization called Flag Ship Trust. After being renovated and refitted, it was put into service in June 1988. The ship is used by the Church of Scientology for advanced Scientology training in “Operating Thetan” levels, as well as for spiritual retreats for its members. Curaçao has been the ship’s homeport since it was purchased by the Church of Scientology.

According to his 2001 statement, Lawrence Woodcraft had been an architect in London, England since 1975, and joined Scientology’s elite “Sea Organization” (Sea Org) in 1986. He wrote that he was asked by the Sea Org to work on the Freewinds in 1987, and during his work on the ship “noticed a powdery blue fibrous substance approximately 1 ½” thick between the paint and the steel wall,” which he believed to be asbestos. He also discovered what he thought was blue asbestos in other parts of the ship, and reported his findings to Church of Scientology executives. Woodcraft discussed his experiences in a 2001 interview published online by the Lisa McPherson Trust, a now-defunct organization which was critical of the Church of Scientology.

Church of Scientology spokeswoman Karin Pouw responded to Radar Online about the asbestos reports, in an email published in an article in Radar on May 1. “The Freewinds regularly inspects the air quality on board and always meets or exceeds US standards,” said Pouw. She stated that two inspections performed in April “confirmed that the air quality is safe,” and asserted that the inspections revealed the Freewinds satisfies standards set by the United States Occupational Safety and Health Administration and the U.S. Clean Air Act.

Pouw told Radar that “The Freewinds will be completing its refit on schedule.” The Church of Scientology-affiliated organization Citizens Commission on Human Rights (CCHR) had been planning a cruise aboard the Freewinds scheduled for May 8, but according to Radar an individual who called the booking number for the cruise received a message that the cruise had been delayed due to ongoing work on the ship. Citing an article in the Netherlands Antilles newspaper Amigoe, Radar reported on May 6 that a team from the United States and supervised by an independent bureau from the Netherlands traveled to Curaçao in order to remove asbestos from the Freewinds.

“I stand by everything I wrote in my 2001 affidavit,” said Lawrence Woodcraft in an exclusive statement given to Wikinews. Woodcraft went on to state: “I would also comment that if the Church of Scientology claims to have removed the blue asbestos, I just don’t see how, it’s everywhere. You would first have to remove all the pipes, plumbing, a/c ducts, electrical wiring etc. etc. just a maze of stuff. Also panelling as well, basically strip the ship back to a steel hull. Also blue asbestos is sprayed onto the outer walls and then covered in paint. It’s in every nook and cranny.”

Many Scientologist celebrities have spent time aboard the Freewinds, including Tom Cruise, Katie Holmes, John Travolta, Kelly Preston, Chick Corea, Lisa Marie Presley, Catherine Bell, Kate Ceberano, and Juliette Lewis. Now magazine reported that Tom Cruise has been urged to seek medical attention regarding potential asbestos exposure, however a representative for Cruise stated he has “absolutely no knowledge” of the recent asbestos controversy. Cruise, Holmes, Travolta and Preston have celebrated birthdays and other events on the Freewinds.

In a May 15 statement to the United Kingdom daily newspaper Metro, a representative for the Church of Scientology said that “There is not now and never has been a situation of asbestos exposure on the Freewinds.” The Asbestos and Mesothelioma Center notes that agencies have recommended anyone who has spent time on the Freewinds consult with their physician to determine if possible asbestos exposure may have affected their health.

Raw blue asbestos is the most hazardous form of asbestos, and has been banned in the United Kingdom since 1970. Blue asbestos fibers are very narrow and thus easily inhaled, and are a major cause of mesothelioma. Mesothelioma is a form of cancer which can develop in the lining of the lungs and chest cavity, the lining of the abdominal cavity, or the pericardium sac surrounding the heart. The cancer is incurable, and can manifest over 40 years after the initial exposure to asbestos.

“This is the most dangerous type of asbestos because the fibres are smaller than the white asbestos and can penetrate the lung more easily,” said toxicologist Dr. Chris Coggins in a statement published in OK! Magazine. Dr. Coggins went on to note that “Once diagnosed with mesothelioma, the victim has six months to a year to live. It gradually reduces lung function until the victim is no longer able to breathe and dies.”

Over 1,600 volunteers registered to help build approximately 65,000 of the 500,000 sandbags to create dikes 20.5 feet (6.2 meters) high to protect the City of Winnipeg, Manitoba in the war against the Red River of the North flood.

700 volunteers answered at the rural municipality of St. Andrews alone. Once sandbags are filled for West St. Paul, St. Andrews, and Selkirk, then frozen culverts must be cleared.

The height of the river is expected to be Thursday, and predictions are that it will be less than Flood of the Century of 1997. There is no precipitation in the forecast, and snow in the province should be melted by the end of the week.

“The fear right now is we have to get that ice out of the river. The Amphibex [Excavators] are still working and breaking the ice apart, and everyday we buy with the warm weather and the current, it is thinning the ice down a bit, so when it does start to move, the better chance it’ll move right out into the lake,” said Paul Guyder, the emergency coordinator for the RMs of St. Andrews and St. Clements.

“I feel that we’ve done everything humanly possible to get ready,” said Gary Doer, Premier of Manitoba, “But … there are fallibilities with human behaviour. We can take every preventative measure as human beings possible and we can still get Mother Nature proving again she is superior.”

Communities with ring diking will partially or fully close their dikes at the beginning of the week. Provincial officials are considering opening the Red River Floodway gates around mid-week before ice is fully melted.

Ice jams could cause flooding within the city, however opening the gates could spare neighbourhood flooding when the river rises to the estimated 6.3 meters (20.7 feet) height. The province does have back up plans for dealing with ice jams within the city if they do occur. The unpredictability of ice jams and the ensuing water level rise may cause neighbourhood flooding. The city is raising dikes where the river has jammed with ice in the past such as on tight curves and past bridges. Likewise there are excavators and backhoes positioned at these points.

Vulnerable neighbourhoods on the river banks have been reinforced with sandbag dikes at vulnerable areas from the massive volunteer effort over the weekend. Guyader feels no more extra volunteers are needed, however volunteers are still being asked to leave their names and number in case of unpredicted need. Existing personnel will assess roads, and help with clean up.

Approximately 400 of the 800 people who evacuated the Roseau River Anishinabe First Nation have returned to their homes.

Former Premier, Dufferin Roblin, brought forward the floodway as a protection for Winnipeg residents and economy following the 1950 Red River Flood. The Red River floodway, “Duff’s Ditch” was finally finished in 1968, and its floodway gates have been opened 20 times saving Winnipeg from an estimated CA$10 billion in damages. The floodway expansion began in 2005 at a price of $665 million.

Polish and Chinese experts have come to survey the Red River Floodway, and Dennis Walaker, mayor of Fargo, North Dakota recognises the need for Red River flood defences down river. “Every town that you drive by from the Canadian line up to Winnipeg is either elevated or ring-diked,” said Walaker.

According to multiple reports, India recorded its 14 millionth case of COVID-19 and new infections of over 200 thousand on Thursday, causing multiple hospitals running on full capacity.

The 200739 new infections is twice what was seen during its last peak in September, rising after the superspreading events such as political rallies in local and state elections and religious events, official complacency and highly infectious new variants of the virus. According to Reuters, the government blamed wilful disregard of social distancing measures and face mask mandates. A Railway Protection Force officer told The Telegraph (Kolkata) “[t]he number of unmasked passengers was much more last month. The renewed surge in Covid numbers has triggered some caution but many are still without masks.”

According to CNBC, India overtook Brazil as the second-most infected country on April 12, though still behind the United States. The new strain has forced hospitals into drastic measures, including two or three patients sharing a bed at Lok Nayak Hospital and converting over a dozen hotels and banquet halls in New Delhi into COVID-19 treatment centres. The states Maharashtra, Madhya Pradesh and Gujarat among others have reported a shortage of oxygen; India Today reported on the Ahmedabad Medical Association pleading the state government for oxygen, writing to Gujarat chief minister Vijay Rupani “[i]f such conditions persist, the death toll will rise, violence against doctors will increase and doctors will be forced to shut down their hospitals due to lack of oxygen supply”.

Nationally, the government has shifted its focus from vaccine exporting to domestic production, entering 114 million jabs in peoples’ arms — the third-most, behind the US and China — and three million on Wednesday after recently approving for emergency use its third vaccine: Russia-developed Sputnik V. The government maintains there is not an oxygen shortage and that the primary issue with distributing inoculations to states is over-planning, not a supply shortage.

New Delhi announced stay-at-home orders and shuttered restaurants, malls, gyms and spas, with an exception for movie theatres at limited times and at limited capacity. Mumbai went further Wednesday, closing most industries, businesses and public places and restricting movement of people amidst a surge of labourers to the city. In addition to many cities and towns, the epicentral city of Maharashtra imposed a curfew, with only essential services open between 8pm and 7am. The Central Board of Secondary Education (CBSE) Class 10 exams have been cancelled, and Class 12 exams postponed.

There has also been 1038 new deaths, adding to the total death count of over 173 thousand and putting a strain on local cremation centres and burial grounds. It remains fourth in its death count after the US, Brazil and Mexico.

Joshua J. Goyette allegedly confessed to breaking into a Saxonburg, Pennsylvania retirement home and beating 86-year-old Gertrude “Trudy” Johanson in the early morning of June 25, 2005. The crime, which shocked the small community north of Pittsburgh, was not the only one which occurred recently at area retirement homes. Goyette is also suspected in a May incident where another apartment at the Commons of Saxonburg was broken into through a first floor window and the 90-year-old woman inside was groped while she slept.

Goyette, 25, has addresses listed in court documents in New Bedford, Massachusetts; and in Saxonburg, Pennsylvania, his mother’s home.

The alleged confession was given last Thursday, June 30, 2005, in New Bedford, Massachusetts, to Pennsylvania state police investigators. Goyette is currently being held in the Butler County prison in lieu of $300,000 cash bond. He faces charges of attempted homicide, aggravated assault, burglary and criminal mischief.
