Growing Pains for Google+
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.
Google+ product chief Vic Gundotra, in response to a bug that caused many users to receive multiple notifications, whether or not they were turned off.
