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.

United States swimmer Michael Phelps has been banned from competition and his training stipend revoked for three months by USA Swimming after Phelps was photographed smoking from a glass pipe, often used for smoking cannabis. The picture was published last Sunday by British tabloid News of the World.

USA Swimming, which is the governing body of swimming in the United States, however said that no “anti-doping” rules had been violated.

“This is not a situation where any anti-doping rule was violated, but we decided to send a strong message to Michael because he disappointed so many people, particularly the hundreds of thousands of USA Swimming member kids who look up to him as a role model and a hero,” it stated. “Michael has voluntarily accepted this reprimand and has committed to earn back our trust.”

The suspension will end in time for Phelps to train for the US Championships, which are to be held on the 7th of July.

Phelps has also lost sponsor Kellogg, who said that it would not renew its deal with the swimmer next month.

Phelps won a record eight gold medals at the 2008 Olympic Games in Beijing last year, and has since become one of the world’s most famous athletes.

Anna Nicole Smith, who was born as Vickie Lynn Hogan, was found unconscious in the Seminole Hard Rock Hotel and Casino in Hollywood, Florida in her 6th floor hotel room. One of her attorneys has confirmed that she was pronounced dead at a hospital less than an hour later. She was 39.

Paramedics are reported to have performed CPR on the actress and had to have breathing equipment inserted into her chest after a nurse found her passed out in her hotel room and witnesses say that Smith was receiving CPR while the ambulance took her to the hospital around 2:00 p.m. [EST]. Smith’s bodyguard is reported to have given Smith “cardiopulmonary resuscitation” before paramedics arrived.

“I can confirm that she is deceased. It’s as shocking to me as to you guys. I don’t know what the cause was. This is just tragic and that’s all you can say right now and I don’t know anything further,” said one of Anna Nicole’s lawyers, Ron Rale.

Smith was taken by ambulance to Memorial Regional Hospital and “checked in Monday [to the hotel] at 8 p.m. as a guest. She was due to check out tomorrow,” said cafe spokeswoman, Danielle Giordaano.

“Our rescue crews got there, and they were escorted to a bedroom, where they found a female alone in her room and unresponsive. We then began our normal protocol for dealing with a non-breathing individual. The victim never regained consciousness and we continued with CPR and all life-support methods right up until the time we delivered her to the hospital and then the hospital takes over,” said a spokesman for the responding paramedics team. Smith was pronounced dead at the hospital at 2:49 p.m. [EST].

According to Broward County Medical Examiner’s Office investigator, Edwina Johnson, an autopsy will be performed on Smith on Friday and that her death is currently being investigated. Authorities are not yet treating her death as a crime.

One of Smith’s attorneys, Howard K. Stern, is reported to have been staying with Smith in her room, but authorities have yet to locate Mr. Stern. Mr. Stern is identified by TRIMSPA as Smith’s husband.

“He was here with her. I don’t know where he’s at right now,” said Charlie Tiger the chief of the Seminole Police Department also adding that Smith’s 5 month old baby was not with them.

Smith was a spokeswoman for the company TRIMSPA when she passed, and TrimSpa has removed all content from their site for now, shutting it down and posting only a message in response to her death.

“Today, Anna Nicole Smith’s grief stricken and tumultuous personal life came to an end. Anna came to our Company as a customer, but she departs it as a friend. While life for Anna Nicole was not easy these past few months, she held dear her husband, Howard K. Stern, her daughter, Dannielynn Hope, her most cherished friends, beloved dogs, and finally, her work with TRIMSPA. Anna knew both the joy of giving life, and the heartache of losing a child. We pray that she is granted the peace that eluded her more recent days on earth, and that she find comfort in the presence of her son, Daniel,” said the statement on TRIMSPA’s website posted by Alex Goen, CEO and Founder of TRIMSPA.

Smith was rushed to the hospital in November of 2006 after she was suffering from symptoms of pneumonia. Smith’s son, Daniel Smith, died on September 10, 2006 shortly after Anna gave birth to a baby girl 5 months ago.

Smith was shopping for a new boat in Florida and reports say she felt ill and had a fever for at least a day.

Top broker and Wall Street adviser Bernard L. Madoff, aged 70, was arrested and charged by the FBI on Thursday with a single count of securities fraud, also known as stock fraud and investment fraud. He allegedly told senior employees of his firm on Wednesday that his $50 billion business “is all just one big lie” and that it was “basically, a giant Ponzi scheme (since at least 2005).” Mr. Madoff faces up to 20 years imprisonment and a fine of up to $5 million. FBI agent Theodore Cacioppi said Mr. Madoff’s investment advisory business had “deceived investors by operating a securities business in which he traded and lost investor money, and then paid certain investors purported returns on investment with the principal received from other, different investors, which resulted in investors’ losses of approximately $50 billion dollars.”

The former chairman of the Nasdaq Stock Market is also the founder and primary owner of Bernard L. Madoff Investment Securities LLC, the closely-held market-making firm he launched in 1960. The firm is one of the top market maker firms on Wall Street. He founded his family firm with an initial investment of $5,000, after attending Hofstra University Law School. He saved the money earned from a job lifeguarding at Rockaway Beach in Queens and a part time job installing underground sprinkler systems.

A force in Wall Street trading for nearly 50 years, he has been active in the National Association of Securities Dealers (NASD), a self-regulatory organization for the U.S. securities industry. His firm was one of the five most active firms in the development of the NASDAQ, having been known for “paying for order flow,” in other word paying a broker to execute a customer’s order through Madoff. He argued that the payment to the broker did not alter the price that the customer received. He ran the investment advisory as a secretive business, however.

Dan Horwitz, counsel of Mr. Madoff, in an interview, said that “he is a longstanding leader in the financial-services industry with an unblemished record; he is a person of integrity; he intends to fight to get through this unfortunate event.” Mr. Madoff was released on his own recognizance on the same day of his arrest, after his 2 sons turned him in, and posting $10 million bail secured by his Manhattan apartment. Without entering any plea, the Court set the preliminary hearing for January 12.

Madoff’s hedge fund scheme may rank among the biggest fraud in history. When former energy trading giant Enron filed for bankruptcy in 2001, one of the largest at the time, it had $63.4 billion in assets. The scheme would dwarf past Ponzis, and it would further be nearly five times the telecommunication company WorldCom fraud and bankruptcy proceedings in 2002.

The Securities and Exchange Commission filed a separate civil suit on Thursday against Bernard L. Madoff Investment Securities and its eponymous founder Mr. Madoff. It was docketed as “U.S. v. Madoff,” 08-MAG-02735, by the U.S. District Court for the Southern District of New York (Manhattan). SEC, New York associate director of enforcement, Andrew M. Calamari, asked the judge to issue seizure orders on the firm and its assets, and appoint a receiver. The SEC pleads, among others, that “it was an ongoing $50 billion swindle; our complaint alleges a stunning fraud that appears to be of epic proportions.” It further accused the defendant of “paying returns to certain investors out of the principal received from other, different investors” for years. Madoff’s hedge fund business had previously claimed to have served between 11 and 25 clients and had $17.1 billion in assets under management. But virtually all of the assets were missing.

United States District Court for the Southern District of New York Louis L. Stanton on Thursday appointed Lee Richards, a Manhattan lawyer, as the firm’s receiver. A hearing is set for Friday, for a ruling on the SEC’s petition to grant plenary powers to the receiver over the entire firm, and an absolute asset sequestration.

Doug Kass, president of hedge fund Seabreeze Partners Management said that “this is a major blow to confidence that is already shattered — anyone on the fence will probably try to take their money out.”

An undercover investigation by Naperville, Illinois law enforcement has led to the arrest last Thursday of four people allegedly involved in prostitution. The stings came after police received tips that people were using websites like Craigslist and Backpage.com to sell sexual performances in Naperville hotels. 

Patricia H. Scoleri of Naperville was arrested after an unidentified neighbor observed consistently suspicious activity at Scoleri’s home. Traffic was unusually heavy and consisted mostly of luxury cars in an otherwise quiet, middle-class neighborhood. Also, the visitors were mainly middle-aged men, and an odd string of lavender-colored lights were hung on the front window.

Police say Scoleri worked alone. She was arrested at 2 p.m. local time (2000 UTC) and is charged with violation of anti-prostitution laws, anti-cannabis laws, and the Massage Licensing Act. She apparently has four children, but the Illinois Department of Children and Family Services has neither contacted her nor received a police report on her.

The second sting occurred at 5:30 p.m the same day (2330 UTC) and resulted in the arrest of Chicago resident Tonya M. Adams. She is charged with prostitution and driving without a license. Another sting about an hour later resulted in the arrests of Jessica M. Walley, a Skokie resident, and Mark A. Williams, a self-admitted Schaumburg gang member. “Walley was charged with prostitution and unlawful possession of cannabis. Williams was charged with pimping, obstructing a peace officer, driving with a suspended license and driving without insurance,” reports WBBM News Radio 780.

All four suspects are free, having paid the required ten percent of their $1,000 bail. They may face additional charges related to crack cocaine discovered during the police investigation. Arraignment is scheduled for next month at the DuPage County Circuit Courthouse in Wheaton.

John Mark Karr, the man who last week admitted to killing six year-old JonBenét Ramsey on Boxing Day 1996, has been told by a judge that he will be sent to Colorado to face charges.

On Monday, the forty-one year-old American teacher was extradited from Bangkok in Thailand to California. From there he will fly to Colorado within the next few days, and it is expected that he will be formally charged with murder, sexual assault and kidnapping.

JonBenét, a beauty queen, was found beaten and strangled to death in her Colorado home on the day after Christmas in 1996.

In a press conference last Wednesday, Karr confessed to being with JonBenét when she died, adding that her death was an accident. “I was with JonBenét when she died. I loved JonBenét. She died accidentally. I am so very sorry for what happened to JonBenét. It’s very important for me that everyone knows that I love her very much, that her death was unintentional, that it was an accident.”

Despite his confession, Karr’s then ex-wife said that he was in Alabama with her when the murder occurred.

Former American Idol winner Ruben Studdard has won a lawsuit and $2 million against his ex-manager Ronald W. Edwards and Edwards’ promotions company, Sez Inc. The lawsuit was for misappropriating the singer’s money and credit cards. The suit claimed Edwards misused more than $246,000 of the singer’s money. According to the judge’s ruling, Edwards stole money from Studdard’s checking and other bank accounts, improperly used his credit cards and even used Studdard’s money to repay a $10,000 bank loan.

Jefferson County Circuit Judge Scott Vowell awarded Studdard $500,000 for actual losses and another $1.5 million in punitive damages. Vowell dismissed Edwards’ promotions company from the suit because it was bankrupt and had no money or assets. Edwards filed a petition for Chapter 7 bankruptcy on June 17, 2005. Studdard has sold 2.2 million records, but because of the damage done to his credit by Edwards, it is now even hard for Ruben to buy a home, said Vowell.
