TWTC TCP/IP Transit and Peering event on Sunday, September 18, 2005

Summary & Impact:

At approximately 12:50pm MDT on Sunday, September 18, 2005, The TWTC
TCP/IP network experienced network congestion due to failures of some
Transit and Peering routers.  Several services were interrupted
including DIA/EIS, ENLAN and L3 VPN.

Transit and Peering routers failed during this outage, which caused
numerous peering/connectivity issues between TWTC's network and many of
our peering partners.  TWTC internet customers (DIA/EIS) may have been
impacted by this outage.  This also may have affected customers on other
provider networks trying to reach destination hosts (websites/servers)
which reside on TWTC's network.  ENLAN and L3 VPN customers may have
lost connectivity during the outage.

At  approximately 2:16pm MDT, TWTC TCP/IP Operations & Engineering
personnel had recovered a majority of the affected Transit and Peering
routers. 

At approximately 2:30pm MDT, All peering and VPN services were
completely restored. 

Corrective Actions:

TWTC is continuing to work with our vendor to determine a root cause and
a permanent corrective solution.  TWTC continues to monitor Transit and
Peering routers and the TCP/IP network.
