Google's mail and application services are unavailable to some users. The company says it's investigating the problems, but doesn't know their cause.

Google's apps status dashboard shows that its Mail, Drive file storage service and office-application services are "disrupted." Its administrator control panel, which lets companies manage their Google applications, is completely down.

The disruptions started affecting people worldwide around 8 a.m. Eastern time.

Google Inc. says it's "working hard to restore normal operation."
