Tuesday's change was not the first time that Harvard Arts and Sciences Computer Services (HASCS) has placed restrictions on network access.
In October, HASCS restricted Napster access by limiting outbound network traffic for the music-sharing service.
But Davis said that Napster has since then found ways to get around such restrictions, and he emphasized that other websites such as Scour.com, Gnutella and CuteMX, have gained a place in the hearts of Harvard students--and have contributed to clogging up the network in the process.
