1/25/2017 7:20am – This morning technicians discovered a hardware failure on the Columbia campus core firewall. This has been creating a variability in traffic response performance since Saturday. It was identified this morning that last night the routing processor pegged at 100% and was becoming somewhat non-responsive. To avoid the potential global impact the partial fail over that automatically occurred on Saturday was manually completed at 7:16am. There was some impact until 7:18am, when operation appears to have returned to normal.
