Curious… why did you wonder if they have Brocade routing gear? Wondering what prompted you to ask about that particular brand… Should I be worried about something?
If you run any TCAM based system and take full BGP tables on them, then, yes, you: A: should be worries and / or B: should have started trimming tables to fit in CAM and / or C: should have started fiddling with the CAM sizing / layout and / or D: be chatting with your vendor and checking the CAM size on your line cards. There is no evidence yet that it was CAM exhaustion vs any of a whole bunch of other failures, but hey, now at least you know to start looking :-P W

nice.. this doesn't make sense
It does make sense from UK traffic perspective, some AS's worked for queries, some AS's did not get a connection at all.
