Brief outage on web11 server February 2, 2013 (resolved)
There was a brief outage on the web11 server today at about 2:42 PM Pacific time.
This was caused by a “denial of service” attack that increased the incoming network traffic to that server from the usual 5 Mbps or so to over 350 Mbps. Servers other than web11 were not affected.
This appears to be very similar to the attacks that occurred last Monday morning.
We are closely monitoring all systems so that we can see exactly how to block future attacks.
