Gmail outage caused by overloaded servers

A worldwide outage of Google's Gmail online e-mail system on Tuesday was caused by a traffic jam on its servers, according to Google's official Gmail blog.

The problem was that some recent changes designed to improve traffic flow on request routers, servers designed to direct Web queries to the appropriate Gmail server, overloaded the system after workers took some Gmail servers offline to perform routine upgrades.

The overload resulted in people around the world being unable to access Gmail for about 100 minutes, Treynor said, though he noted that IMAP/POP access and mail processing continued to work normally.
