Opalstack - Incoming mail problems in Germany – Incident details

The disk array rebuild is complete and the server has been stable since our last update.

The DE mail service is back online at this time. The main issue was heavy load caused by the very high volume of deferred mail the resulted from the mail loop. This was exacerbated by the degraded disk array.

The networking issue was unrelated but has been resolved.

The disk array is still rebuilding but the server is operating normally. We'll continue to monitor until the rebuild is complete.

There seems to be multiple issues related to the DE IMAP server:

1. A forwarding loop was causing delivery delays for the past few hours.
2. A degraded disk array was impacting system performance
3. A failed network switch is currently blocking network connectivity

Our data center team is working on restoring connectivity at this time.

The DE IMAP server is now offline for a filesystem check.
