History: lengthy outages

That was a different one, but I didn't have that data readily available.
The cisco/bay bug I was thinking of was when Cisco's kept reseting all
their BGP sessions when they saw a particular announcement from Bay routers.

IIRC (or maybe we're thinking of different outages), it was reversed.
There was an advertisement with a malformed AS_PATH attribute "out
there", Cisco's accepted it and passed it on (still in malformed form),
but Bay's (and some other non-Cisco implementations, such as gated)
correctly issued a Notify message and dropped the session upon receipt
of the malformed advertisement.

I believe there were two such outages (separated by a year or so)
before Cisco fixed the bug.
