Last night, around 5pm, advertisers were unable to login to the Google AdWords console to manage their ads. The downtime reportedly lasted about an hour.

There were threads at Google AdWords Help and WebmasterWorld amongst others. The AdWords help had an official post from Google confirming the bug and when it went back online.

AdWords users and support was active on phone support, online forums and Twitter responding to concerned advertisers.
