An issue occurred today, while migrating the auvious.video DNS zone to Google Cloud DNS. A missing DNS alias entry caused our European service to malfunction for several minutes. This was not detected by the monitoring system, because it uses a different (not an alias) DNS entry to check the liveness of the system. The missing alias was added, but also the system configuration was updated to not use the alias, in order to avoid any more downtime due to DNS caching of missing entries.
We're sorry for any inconvenience, and we're currently making sure to update our systems in order to avoid any similar situations in the future.
