Excerpted from an email from the head of MIT’s Telephony Services to MIT Information Systems, sent today at 3:40 pm:
We are experiencing a saturation of the telephone network in Eastern Massachusetts which is resulting in some local telephone calls receiving a "fast busy." At 3pm today, RED SOX tickets for the World Series went on sale, and as a result, the local telephone trunks are completely at capacity. There is no outage, simply a saturation. The last time this happened was on September 11, 2001.
