Tomorrow (13 December) we will reinstall the authoritative DNS server
authdns0.csx.cam.ac.uk 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 authdns1.csx.cam.ac.uk and for
ipreg.csi.cam.ac.uk (the primary server).
During these upgrades the servers will have their hostnames changed to
auth0.dns.cam.ac.uk, auth1.dns.cam.ac.uk, and pri0.dns.cam.ac.uk,
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.
