According to the OIT, the issue is as follows: "Network monitoring has shown that many iPad devices are causing a problem on the campus network. These devices are continuing to use an IP address they have been leased well beyond the time they should."
The OIT says users who keep trying to connect may find their devices blocked, so that the stability and reliability of campus network services can be maintained.
This is not the first time iThings have run afoul of higher learning's network wonks. Duke University suffered network outages around the release of the iPhone in 2007 and blamed those on the iPhone invasion; those hiccups eventually turned out to be a problem with Cisco routers, not Apple's phone.
