We are aware of an issue preventing some users from logging into Sitebeam and WebScan. Amazon is upgrading some databases we use, and that is causing the interruption in service. We will be monitoring the situation and will update this page as we know more.
Sitebeam is now back up and running, we are waiting on the DB upgrade for WebScan to finish.
WebScan came back up last night, all users should be able to log in and run reports as usual.
