The service that ns1.tornevall.net relies in runs an older version of OpenVZ which will reach an end of support 2023-12-31. Therefore, we will prepare to transfer this service elsewhere, probably already during this summer. If your DNS services depends on this, make sure you’re no longer using it.
The work has recently also started to migrate to a new master DNS. This work was finished today, which means that the API (v3) as of today communicates with a DNS that has closer reachability.
