Ed, We had one of those also. Insurance agent office in downtown Manhattan. On site AS400 to manage business. Response time fluctuations at this site were off the scale. ATT said everything was great on the line, one of the best drops in our network. 6 of us were working with the agents in that office when we finally realized that response time was great before 9:00 AM and after 4:00 PM. Same hours as New York Stock Exchange. ATT finally admitted they had been working on upgrading the local switches to handle the huge increase in traffic to NYSE, which was 2 blocks from this office.
