Network slowness

From Jeff’s email: “Around 11:15-11:30 something happened that crippled the res-hall network to the point of unusability. We made a change to revert something to the way it was around four months ago and that seems to have solved the problem. Our two outstanding questions are, did that fix it? and if so, Why was it not broken for four months? It may be the case that it is not really fixed, but rather went in to remission until some later time. We are still attempting to track down more information to provide a better explanation.”
