I see the Cogent link is not taking any traffic -

        http://www.net.berkeley.edu/newcricket/cricket/inr-668.html

- despite the Server status page showing all servers are running. 

        http://setiathome.berkeley.edu/sah_status.html

This appeared to happen about three quarters of an hour ago.

Cannot see any reason for the loss of connection.
