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.

There are a whole bunch of interesting problems I remember, but can't
find the date.

There was the Sprint "" route problem. There was the 129/8 which
happened shortly after AS7007. There was an ANS bug in the ENSSs which
knocked them out.

I tried not to include "malicious" acts, such as DDOS since I think they
should be considered separately. Although I recognize often the underlying
cause of the security issue may be related to operational error or bugs.
