Even Area 51 has DACS problems

[Sean Donelan <sean () donelan com>]

Sprint filed an outage report covering Area 51 (yes, that Area 51)
last week.   A circuit breaker was turned off disrupting 8 DS3s,
long distance and "special services."  Full details are not known.
Power was restored to the DACS shelf and service restored after
about 5 hours.
