CATMA 7
14 May 2026, 23:30 CEST [completed] – Pardon the interruption, we need to install some updates and reboot our systems. CATMA will be back in a few minutes.
07 May 2026, 19:00 CEST [ongoing] – We are still investigating a problem impacting CATMA. You may experience intermittent connectivity or problems accessing the CATMA application, as well as problems with particular functions or a lack of feedback in the user interface.
If you get disconnected / logged out and are unable to log back in, you can try to delete the site data for (app.)catma.de in your browser settings. The inability to log back in is usually temporary.
Unfortunately, due to its intermittent nature, the cause of the problem is proving difficult to track down. We believe that it may have been caused by a change at the network infrastructure level at the end of March, and initial testing unfortunately did not surface it. We are also considering reverting the aforementioned change, however further testing is required first.
We apologize for the inconvenience that this problem is causing for our users. Solving it is our top priority. Thank you for your patience!
