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.

Managed Server Version 7: Web Application Firewall: Additional Rules to mitigate CVE-2021-44228 (Log4j)

Our web application firewall does already detect all known exploits targeting arbitrary GET and POST parameters (CRS rule 932130). However, the rule did not inspect HTTP headers such as the user-agent and referrer yet.

To mitigate attacks against this vulnerability, we

  • added the User-Agent and Referer headers to the targets of the CRS rule 932130
  • added another, targeted rule against the usage of jndi strings

Even though the web application firewall does protect your applications from this issue unless manually disabled, make sure to take the required steps to mitigate the problem at its source, as outlined by Log4j here.
