The NSDNET technicians are still working to isolate the trouble. The NSDNET technicians tried bringing down the r2dnvr100 router to force the traffic to the r2dnvr101 router. However, this did not resolve the issue. The r2dnvr100 router was brought back up. There is no ETTR available at this time.

Technical teams continue to segment and test the various links and platforms in Denver. The BVoIP team re-pointed the Call Control Element from Atlanta to Philadelphia. Call completing has improved, however some blocked calls are still occurring.

The issue appears to be related to a message storm in the EIGRP protocol, which is used by the various routers to communicate between themselves and the various external end points (centers and elements).

Web conferencing services continue to have impacts due to heavy backups at the top and bottoms of the hours for both ATT Connect and ATT Web Meeting services. Customers may be experiencing delays and synchronization issues.

Our BVOIP service in Troy, MI seems to be mostly working now.  Getting an occasional "call cannot be completed" for some DIDs but I would say 90% of DIDs are ringing through to us now.  This outage seemed to only affect our DIDs inbound.

NSDNET technical teams continue to investigate the trouble. Teams are currently focused on one of the Denver campus routers, specifically one of the high speed slots may be failing. There is no ETTR available at this time.
