DSL.net Launches New DS-3 Service for Businesses

NEW HAVEN, Conn.--(BUSINESS WIRE)--March 9, 2004--DSL.net, Inc. (NASDAQ: DSLN - News), a leading nationwide provider of broadband communications services to businesses, said today that it has added a new high-speed connectivity offering of up to 45 megabits (Mbps) to its product portfolio for business customers with extensive bandwidth needs.

The new offering, called NETgain 45, is a DS3-based, high-bandwidth, broadband Internet connection that includes DNS management, routable IP addresses and 24/7 technical support. This high-speed connection is ideal for businesses that are running high-bandwidth applications or those with a virtual private network (VPN) that includes a large number of locations.

"Formally adding a DS-3 service to our product portfolio is a natural progression for DSL.net. We have substantially expanded our network reach and increased network capacity as a result of strategic acquisitions during 2003," said Keith Markley, president and chief operating officer of DSL.net. "In addition to our core SDSL service, we also began offering T-1 service two years ago - and have seen T-1 sales increase significantly during that time. By bringing DS-3 service into our product mix, we can further improve margin, create a new revenue stream and continue to meet the growing bandwidth needs of business customers."

NETgain 45 is offered in fractional speeds starting at 3 Mbps all the way up to maximum DS-3 speeds of 45 Mbps. By comparison, T-1 and SDSL services provide a broadband connection of up to 1.5 Mbps. NETgain 45 is available in select markets. In conjunction with its expanded broadband network, DSL.net already has been provisioning DS-3s for its wholesale data communications customers during the last year. NETgain 45 broadens DS-3 service availability via DSL.net's direct sales force.
