Sorry about the extended lack of DNS updates today.
Unfortunately the VM host system lost the RAID set that held the filesystem for our DNS master server (amongst others). We determined that it would be faster to rebuild some servers from scratch rather than waiting for more intensive RAID recovery efforts.
The DNS master server is set up so it can be rebuit from scratch without too much difficulty - all the data on its filesystem comes from our configuration management systems, and from the IP register and MZS databases.
The main effect of this is that the zone transfers following the rebuild will be full transfers from scratch - incremental transfers are not possible. There is likely to be some additional load which slows down zone transfers while everything catches up.
