Upcoming Scheduled Maintenances

Ticket No.:	10514:45
Subject:	Internet2 IP Network Backbone Circuits ATLA-KANS and LOSA-KANS Maintenance
Affected:	Backbone Circuits ATLA-KANS and LOSA-KANS
Start Time:	Thursday, July 26, 2007, 3:00 AM (0300) UTC
End Time:	Thursday, July 26, 2007, 5:00 AM (0500) UTC
Description:	Internet2 engineers will be inserting the new Internet2 Houston core node into the current ATLA-KANS and LOSA-KANS backbone circuits. The work shouldn't affect any connector traffic, save two 100ms switches as backbone traffic re-routes when the circuits are removed, and subsequently placed back in service with Houston in the path. This work should complete within 5 minutes, though the entire 2 hour window is reserved.
