I was impacted by this this morning. I had ssh and imaps sessions from my comcast address at home to a vps at arpnetworks.com and they all died overnight. But it was a very strange failure. icmp and udp still worked but tcp couldn't make the round trip. And this was true for several different cidr's arpnetworks.com has. But everything worked fine from other locations like from lbl. TCAM is pretty bizarre; I believe access lists use them and one time Bro installed too many and overran the TCAM. This was not straight forward to recover from (e.g. just removing a bunch of ACLs did not unfrob the router). Craig
