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.

Managed Server 7/8: Filesystem Size Changes, scheduled 2 years ago

Up to now, our managed servers did use a large, virtual file system, and the actual space assigned was just a value checked within our monitoring. As this has some storage related drawbacks, we will change the behavior today. As of now, the file system size will be set to the value selected in Cockpit, plus an added buffer of 30 percent. Changes are still possible without reboot, and all tools and checks do reflect the new behavior already. We will monitor the rollout for each system carefully, and do not expect any noticeable changes apart from the new file system total size.
