Data Service Outage 2009
On October 2, 2009, Microsoft lost the ability to access user data for T-Mobile US Sidekick subscribers temporarily. Subscriber data loss included contacts, notes, calendars and photos. Some data was restored within 14 days of the outage, however most of the data was restored between October 8 and the end of November. Early reports stating T-Mobile and Microsoft had "almost certainly as a result of a server failure at Microsoft" proved to be untrue and premature.
Sidekick user data is stored at Danger facilities, now under the ownership of Microsoft. Unsubstantiated reports suggest Microsoft vendor Hitachi, Danger's storage area network (SAN) provider may have had a part in the temporary data loss. Lawsuits against Microsoft claim that Microsoft had inadequate backups or an insufficient disaster recovery plan. Litigation against Microsoft and others is pending as of this writing.
As a result of the outage, T-Mobile suspended sales of all Sidekicks and Sidekick Data Plans until the outage was resolved. Sales and new activations resumed on November 16, 2009.

Famous quotes containing the word data:
“This city is neither a jungle nor the moon.... In long shot: a cosmic smudge, a conglomerate of bleeding energies. Close up, it is a fairly legible printed circuit, a transistorized labyrinth of beastly tracks, a data bank for asthmatic voice-prints.”
—Susan Sontag (b. 1933)
