The source of the report was MCI Worldcom customer service. Due to the number of mergers, it is sometimes hard to keep who has what where straight. Even the employees of the companies involved have trouble. As an outsider, I have no hope of getting everything correct. But here goes. As I understand this, the ATM problem is affecting Worldcom's original ATM backbone, which uses Stratacom ATM switches. Perhaps the reason why worldcom CSC said they were escalating the matter with Cisco is Stratacom is now owned by Cisco. MCI Worldcom CSC only told us the vendor involved was Cisco, not anything about specific equipment models affected. I believe the other ATM networks owned by MCI Worldcom, such as MCI and UUNET are still seperate and aren't directly impacted. I don't know where MFS's network was rolled into. To fix the problem, MCI Worldcom customer service reports they will have to reload all the Worldcom ATM switches this evening between Midnight and 2:00am.
This is interesting. I don't recall their "entire" ATM network being Cisco .. or much of it at all for that matter. What was the source of this report?
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 problem.
I don't know if MCI Worldcom has filed a FCC outage report like AT&T did when their frame-relay network had problem. -- Sean Donelan, Data Research Associates, Inc, St. Louis, MO Affiliation given for identification not representation
