We are seeing performance problem in processing incoming data and are investigating the problem.
Edit 11:14 Europe/Berlin
The database master has high load and causes slowdowns in the processing queue and frontend. We are working on a fix.
Edit 12:07 Europe/Berlin
We found no cause of the load on our database master. Hoster is now investigating if there is a cause outside of our reach.
Edit 12:22 Europe/Berlin
Load has dropped and queues catched up.
