MCI Worldcom had a circuit outage in Indianapolis at about 11:30 CST 
3-Feb-1999.  Since then the MCI Worldcom ATM network has been FUBARed.
MCI Worldcom believes the problem is in some Cisco equipment, and
cisco has issued a patch.  MCI Worldcom will be reloading their entire
nationwide ATM network between midnight and 2:00am hoping to fix the

I don't know if MCI Worldcom has filed a FCC outage report like AT&T
did when their frame-relay network had problem.
