Chesconet Outages on Monday 7/19

The following message comes from Larry Konig at Chesconet:

All Chesconet sites are currently up.


On Monday afternoon, from 2:53PM until 5:04PM, all Chesconet customers experienced intermittent outages in Internet connectivity. The cause of the outages was determined to be excessive processor utilization on one of Chesconet's Internet border routers. This caused the router to repeatedly drop and reestablish peerings with two of our upstream service providers (Cogent and MAGPI), disrupting Internet service for all customers. Configuration changes were made which significantly reduced the CPU load on the affected router, and stable Internet access resumed at approximately 5:05PM.

NOTICE:
On Wednesday morning, July 21, MAGPI will be performing router maintenance starting at 6:00AM. During their two-hour maintenance window, Chesconet will not have Internet2 access. All customer traffic destined for Internet2-connected sites will instead use Chesconet's commodity Internet service with Cogent and Level3.
