Wikipedia suffers global collapse

Overheated servers in Europe and a flawed failover process caused a worldwide crash of its servers

Wikipedia and other Wikimedia Foundation Web sites went down for hours on Wednesday in a global outage caused by a domino effect of technical problems.

The problems started when Wikimedia servers overheated in the organization's European data center and shut themselves off automatically.

Wikimedia then switched all its traffic to its server cluster in Florida, but the failover process, which involves changing servers' DNS entries, malfunctioned, knocking the organization's sites offline around the world.

"Shortly after we did this failover switch, it turned out that this failover mechanism was now broken, causing the DNS resolution of Wikimedia sites to stop working globally," wrote Mark Bergsma, Wikimedia's operations engineer in a post on Wikimedia's Technical Blog.

Google's YouTube video sharing site also reportedly suffered downtime, going offline on Thursday morning, according to news reports.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
