AppId is over the quota
Earlier today members were disconnected from Xbox LIVE and found themselves unable to log back in. This impacted LIVE users on Xbox 360 consoles, those running Zune & Games for Windows LIVE software on PCs, and Windows Phone.
This began just after 9AM Pacific and was resolved roughly two hours later.
The root cause of this outage was human error. A change resulted in an interruption to normal traffic flow within our datacenters, which logged users out and prevented them from logging back in. We’re sorry for this, and we’ll be updating our processes to prevent this from happening again in the future.
If and when issues do occur, we’ll keep you updated through the Status page on Xbox.com and from @XboxSupport on Twitter.
