At about 12:25 pm today (Monday, April 25), staff noticed that several of the WebMail servers were experiencing what appeared to be a denial-of-service attack. The WebMail servers were returned to service at 2:45 pm. During this outage we had to restart the load balancers and AFS servers to clear the traffic in order to restart the servers. These restarts affected several other services, including the public web servers. There could be some residual slowness because of the backlog of mail that has built up.
