Is Gmail down for everybody, down for you alone, or, well, "a small subset of users"? Does Google know about the problems, or should you alert them to their outage?
Fortunately, you can find out whether Google is aware of Gmail service disruptions — login failures, for instance, missing data, or certain functions not working — easily, and check for an estimate on how long the outage will last, too.
