Emergency Service window: Restart of internal nameservers..

As a follow up on the previous mentioned internal DNS outage, a vulnerability was found in the existing configuration. To mitigate, and deploy an update, the operations team need to restart the internal DNS servers. This will happen:

Friday 24th of July, 2026 – 07:00 UTC.

The operation will last for a very short period (minutes). Most systems have a cache for DNS, and it is expected that very few users will notice any issues. Never the less, if you have the possibility, please limit your large operations between 06:55 UTC and 07:10 that day.

We will of course update this post afterwards, when the operation is done and everything is back to normal.
