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

Cluster Maintenance

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

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.
