Yesterday, we reported on the Google keyword tool outage, where the reports were missing search volume data.

The problems actually persisted throughout the day, causing major headaches for advertisers looking to research possible keywords. In any event, a Google representative posted in the WebmasterWorld thread that it would be fixed very soon. The Google rep said at about 2pm (EST):

As of about 5:30pm (EST), we have been receiving reports that the bug is resolved. I have confirmed it works for me, so you can now give it a try over here.
