Yesterday we added a few plugins to our Packeteer that helps prioritize our internet usage. one of those plugins was called Apple iTunes 1.0.0. After installing this plugin I noticed that the iTunes Music Store became extremely slow and mostly unusable. One workaround was to set my system to use our proxy server. While it would be great if everyone used the proxy server, I know there are people on campus that are not using it. So I removed the plugin from the Packeteer and now everything seems fine.
So if anyone noticed problems with the iTunes Music Store yesterday, it was our fault and should be working again.
