Following an operating system update that was applied at 00:37 UTC on 15 November the primary nameserver failed to restart. This was noticed immediately upon completion of the update, and we started troubleshooting.
After extensive research on the likely cause and resolution of the problem we determined that the quickest way to get the nameserver back online was to roll back the update and restore from a back-up. There were some issues with this, however, that necessitated implementing a back-up plan for company email in order for us to gain access to our account at the data centre where the nameserver is hosted. Once this was accomplished the restore was initiated.
The nameserver was back online at 02:28 UTC.
During the time the server was down domain information would have been cached by DNS resolvers that already had a cached copy of the DNS information for your domain. However, it is possible that some incoming email may have been delayed or possibly bounced, or people trying to browse your website would not have been able to see it. For this we apologise.
