All Aster services are back to normal. Services were unavailable or degraded from 08:37 to 11:02 CEST. Mail sent to you during this window is delivered as normal once the senders' servers retry. We're sorry for the disruption.

The disruption is caused by maintenance on the emergency power systems at our hosting provider's data center (Hetzner, FSN1-DC8), which left a storage volume on one of our servers unresponsive. We're monitoring the situation and will restore full service as soon as the server is stable. Hetzner's status: https://status.hetzner.com/incident/846711ea-c512-4e62-ac0b-1b29f057847a

We're seeing errors and timeouts across Aster Mail. Some users may be unable to sign in, load their mailbox, or send mail. We're investigating.
