If we hold BBN to the same standards that the telco industry uses to
come up with 99.999%, BBN was up but "a few customers" experienced a
localized outage. This would be brushed off the same as the Illinious
AT&T fire at the POP that took out much of the Chicago suburbs for
about a week. It doesn't count against the 99.999%. (Otherwise AT&T
owes Chicago a couple thousand years of flawless service:).
I remember my complaint on the IETF list some years back, when
NSFnet/ANS would routinely tout high availability, by eliminating any
link outages from their report, as they were not under its control ...
or route flaps greater than 5 minutes, for unknown reasons.
