Just how popular has Google+ been for the social-networking giant? Enough to add $20 billion in value to the company in some circles.
And it others, popular enough to run out of disk space. Over the weekend, the select few Google+ users may have noticed their notification box being flooded with repeat notification messages.
Google's Vic Gundotra came out and explained the troubles. He said the company's servers in charge of tracking notifications ran out of disk space for about 80 minutes.
"we didn't expect to hit these high thresholds so quickly, but we should have," Gundotra said.
These are the types of things Google hopes to sort out while its social network remains in beta.
