Google's Gmail service is used both by personal and enterprise users, and the service is currently down across the globe. We've confirmed this with employees in our own offices around the United States, and a quick Twitter search shows that it's down in other countries, too.

We've noticed that it is coming in and out, but that it won't allow us to sign into chat or multiple accounts at once. We're not sure what's going on, but we'll keep you up to date if Google offers a reply on the topic.

Update: It appears services have been restored, for now. Our own Joey Davidson also reported that it crashed Chrome browsers.
