22:55 - We are investigating an issue with the Surfprotect cluster and associated DNS servers in London. Today's core network issues appear to have had a knock-on impact to these services. Emergency maintenance will be performed to restart affected processes.
23:15 - Several servers (we use DNS anycast) were found to have an issue following the outage and were not behaving as expected. Following a reboot things are back to normal. Services are back to normal but we will continue to monitor the situation.
