Google+ runs out of disk space, spams users with notifications

Some early adopters of Google+ have found themselves bombarded with multiple notification messages in their email, due to a bug in the social networking's code after the site - astonishingly - ran out of disk space.

Vic Gundotra, Senior Vice-President of Social for Google, posted an apology (appropriately enough) on his Google+ account to those users affected, painting the social network as having been a victim of its own success.

Please accept our apologies for the spam we caused this afternoon.

For about 80 minutes we ran out of disk space on the service that keeps track of notifications. Hence our system continued to try sending notifications. Over, and over again. Yikes.

We didn't expect to hit these high thresholds so quickly, but we should have.

Thank you for helping us during this field trial, and once again, we are very sorry for the spam.
