On Monday, several of Google's apps and web sites like YouTube, Drive, Gmail, and others went down. This left a large number of global users unable to communicate, stream videos, and more. Google blamed the problem on "an authentication system outage for approximately 45 minutes due to an internal storage quota issue." Bloomberg reported on Tuesday that for the second consecutive day, Gmail could not be accessed by a large number of users due to a technical issue. A Google spokeswomen had said on Monday that "We apologize to everyone affected, and we will conduct a thorough follow up review to ensure this problem cannot recur in the future." On Tuesday, the very next day, the problem recurred. Messages being sent were bouncing back to the sender stating "The email account that you tried to reach does not exist."
