FleetMon under attack, AIS reception affected

Starting Saturday evening 16:00 UTC, the FleetMon system finds itself under attack from unknown sources in the Internet that aim to interrupt or stop FleetMon’s services. While our servers have been successfully stabilized in the meantime, AIS reception is affected and not yet back to normal level. Thank you very much for your understanding.
We are working hard to block this kind of attack and identify the source, hopefully restoring full FleetMon coverage during Monday.

Update: AIS Coverage has been fully restored in the meantime. See our following blog post.
