Google said today a storage software update was responsible for causing some Gmail users to lose access to their e-mail data and said full functionality would be restored soon.

Some Gmail users complained yesterday of suddenly and mysteriously losing e-mails, contacts, and folders. Google originally said 0.29 percent of the user base was affected by the issue but has since revised that figure to less than 0.02 percent, or about 40,000 of the service's 200 million accounts.

In an update on the situation this evening, Ben Treynor, Google VP of engineering and site reliability czar, apologized for the inconvenience and said the company expects to have the lost data restored soon.
