Scheduled Maintenance
Migrate Mail-Relay

We will migrate our Mail-Relay to a new server.

  • This affects only a small fraction of managed-servers where that are explicitely configured to use this mail-relay for outbound mail
  • Since we migrate the IP address, there is no need for any configuration change on the managed-servers that send mail via this relay server
  • During the migration the system will be unavailable for a short period of approximately 5 to 10min

Stop maintenance window: 17/03/2026 01:00

Cluster Maintenance

We will update soft- and firmware throughout our cluster. During the update, a higher disk i/o latency is to be expected.

Stop maintenance window: 17/03/2026 02:00

Migration Recursive DNS Resolver Servers

We will migrate our recursive DNS resolver servers to a recent version on new servers.

The servers will keep their IP-Addresses and therefore no configuration change on systems relying on those name-servers for DNS lookups is needed.

We don't expect this change to cause any harm (due to having a redundant pair of nameservers), for the sake of safety we perform the switch-over during our maintenance-window.

This change only affects recursive DNS resolution. Our authoritative DNS servers (name servers) used for domains are not affected.

Mailcow 2026-03

We will update Mailcow to version 2026-03.

Migration Recursive DNS Server, scheduled 4 years ago

We will migrate our recursive DNS server to a recent version on a new server.

  • The DNS servers on all managed servers are changed by us
  • If you have manually set our DNS servers (e.g. in nginx, docker), you will have to change them manually
  • We will run the old DNS server for a few more days and inform affected people if we still se traffic

Old DNS-Server:

  • 2a04:503:0:1008::109
  • 2a04:503:0:1014::68
  • 185.17.70.109

  • 2a04:503:0:1014::69
  • 185.17.70.98
  • 185.169.84.69

This change only affects recursive DNS resolution. Our authoritative DNS servers (name servers) used for domains are not affected.
