Networking issues from yesterday resolved

It looks like the networking issues from yesterday have been resolved.
All told, there were three outages in total. The first was at Sunday 4AM, the second yesterday early afternoon, and another one that followed shortly after. The current theory is the failures were caused by an intermittent failure in a network interface card on one of the lab’s firewall servers. The firewall functions were forced to move to the redundant server across campus, which seems to have stabilized the situation, and will allow the failing one to be repaired.
Thanks for your patience!
