Merit Network Services Update

February 27, 2013

By Elwood Downing

ANN ARBOR, Mich. - Around midnight on Tuesday, February 26, 2013, Merit's Network Support Center began receiving alerts and phone calls from Merit Members reporting that they were experiencing problems connecting to the Internet.

Our Support Center and engineers began analyzing the effect of the problem and determined that it was an issue with one of Merit's core routers/switches located at Merit's POP in Chicago. Merit Engineers were able to determine that it was a packet forwarding problem in the way the packets were being handled on one of our key core routers. Once this was determined, all traffic was moved to a different path and different equipment. Merit has multiple 10 gigabits-per-second (Gbps) connections to the greater Internet (commodity) out of Michigan and was able to move the traffic to other paths that have capacity to handle the traffic load. Merit engineers are reviewing the logs and events leading up to the problem. Once they are able to gather the information Merit will work with the equipment vendor to determine if it was a hardware or software problem on the core router.

Connecting to the greater Internet was fully restored and operational as of 4:52 AM ET. All Merit Members should not be experiencing any network problems connecting to the Internet. If a Merit Member is experiencing a network or service issue, please contact the Merit Support Center immediately at 734-527-5700.

Once Merit engineers are able to determine the core cause of the problem a more detailed report will be sent out to all Merit Members.
