Web113 is under a Distributed Denial of Service attack, which is causing occasional delays and timeouts for all sites hosted there. We are working to rectify the effect of the attack.
No other servers are affected.
Update [4:42 GMT]: What we believed to be a DDoS attacked turned out to be an excessive mount of traffic directed at some extremely large page hosted on the server. We have now taken measures to reduce the impact of this traffic, and the server is back to normal.
