The web server on server NC018 sustained a denial-of-service attack between approximately 14:00 and 18:00 UTC on 7 March. This is why websites on this server were unavailable during this period. No other services (email or nameservers) were affected.
We have implemented improved monitoring of this activity on this server. Additionally, we are in discussions with the data centre to move this server to an improved network infrastructure, a move we hope to implement before the end of March.
We apologise for this disruption.
