Kea DHCP field test in house N

4 years ago 2022-08-10 17:00 UTC
Complete

We are planning to migrate to Kea as our new DHCP server software. Previous tests in more isolated networks have shown that the DHCP server should behave as expected. The next step is a field test where we set up Kea as the DHCP server for house N.

While we are migrating the network to Kea DHCP, users must expect outages of up to 30 minutes, while the configurations on the switches are updated and DHCP relaying for Kea is set up.

Mailserver outage

4 years ago 2022-08-05 22:00 UTC
Fixed

Fixed

4 years ago 2022-08-05 22:00 UTC

Our Mailserver is unable to receive emails from other mailservers or forward emails submitted from users. We are investigating the situation. The current assumption is that the database behind the mailserver might be broken or unreachable.

Update 16:39

We have successfully tested other components which are using the database cluster in question. It is unlikely that the database is the source of the problems.

Update 18:00

We have identified a misconfiguration in the mailserver system. The mailing list software tried to connect to the database using a target IP address, which was not the high-availability IP. Thus, during maintenance on the database cluster, the mailing list software was now unable to connect to the database when that one node with the right IP address went offline.

Resolution

The mailserver config has been adjusted so that the highly available IP address will be used in the future. This should prevent an outage like this in the future.
