Authoritative DNS server rebuilds

2018-12-12 - News - Tony Finch

Tomorrow (13 December) we will reinstall the authoritative DNS server and upgrade its operating system from Ubuntu 14.04 "Trusty" to Debian 9 "Stretch".

During the upgrade our other authoritative servers will be available to provide DNS service. After the upgrade, secondary servers are likely to perform full zone transfers from authdns0 since it will have lost its incremental zone transfer journal.

Next week, we will do the same for and for (the primary server).

During these upgrades the servers will have their hostnames changed to,, and, at least from the sysadmin point of view. There are lots of references to the old names which will continue to work until all the NS and SOA DNS records have been updated. This is an early step in the DNS server renaming / renumbering project.
