The Next Web reports that a number of Google+ users on Saturday have received multiple email notifications, even when users have requested that those notifications be turned off. Some users have reported via Twitter that they have received as many as 50 notifications for just one friend being added to their Google Circle.
Later on Saturday Google’s Vic Gundotra, the head of the Google+ division, posted an apology about the multiple notifications on his Google+ page. He states, “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.”
