As was noted we installed a 2nd GigE between the two switches yesterday. Things are looked good last night we peaked at 1.7Gbps most of that coming from the U's Akamai Stack. Akamai tells me we are maxing out our servers again, it looks like we were maxing them out most of the spring anyway. The Akamai servers are putting out a little less than 2G from about 7am to 11pm. I believe we are seeing more traffic in the evening going to MICE because most of the other Gigapop networks have more of a business day demand curve, so Akamai serves more of the demand out of MICE in the evening as demand from the Gigapop networks slack off. So I think things are much better now, we should get the new switches installed and people moved over but we shouldn't have to rush it. The University will work with Akamai to get more servers over the summer, but I would hope we would have everyone moved over to the juniper switches long before that happens.
