Here's a good one about Cogent. 100BaseTX connection from us to a Cogent Cat3550 ("A"). "A" connects to Houston core router "B". "Normal" Cogent BGP setup: A announces a /32 on B, B announces full table, we announce our prefixes to A and nothing to B. A and B are (supposedly) directly connected. Our BGP session with B flapped numerous times this morning.

Cogent NOCperson said that a flaky router in San Jose had problems, and had to be rebooted. As a result, "you couldn't reach your B peer". Yeah, that makes sense. Oh, and problems in Miami plus the problems in San Jose were causing problems in Boston and New York. Sure.

YMMV, but not a confidence-inspiring answer IMO.
