We are receiving reports that Gmail is down for many users. Users are complaining on Google+ about not being able to access certain email accounts. All other Google products, such as Google+, Google Reader and other features seem to be working fine.
Users trying to access gmail are receiving a servor error, the Numeric Code is 93.
The first outages seem to have occurred at approximately 12:50am EST. At the time of this writing over 20 minutes later, the problem still is being reported.
Right now there is no word on the cause. The hacker group known an Annonymous has never threatened to take down gmail.
We have not confirmed this, but think there might be problems at Google's headquarters in Mountain View, California.
