US Signal

US Signal, a leading provider of data bandwidth capacity in the Midwest, today announced that it is significantly expanding its long-haul fiber network throughout Ohio. This expansion will add 1,000 miles of long-haul fiber to the US Signal network, one of the largest in the Midwest.

The announcement marks the Company’s second expansion in Ohio in six months, following network
growth in Toledo in March 2009. In addition to new colocation facilities and points of presence (POPs),
US Signal is also building into four existing data centers in Ohio.

Newest POPs:

• Cleveland, Ohio (CLEVOH62)
• Cincinnati, Ohio (CNCNOHWS)
• Columbus, Ohio (CLMBOH11)
• Dayton, Ohio (DYTNOH22)

“The addition of these major data centers and POPs, signifies our commitment to providing traditional
protected services, such as Private Line circuits, Internet and MPLS VPNs, as well as cutting-edge
Switched Ethernet services to the entire Ohio market,” said Daniel Olrich, US Signal’s chief operating
officer. “Our Virtual Ethernet services are unique, because they are not constrained to LATA or state
boundaries. We are able to deliver a fully functional meshed switched Layer 2 and/or Layer 3 network
regardless of location or speed.”

The addition of this long-haul fiber will be complemented with the lighting of metro rings in the major
metropolitan areas of Ohio in 2010. US Signal’s network now includes more than 6,000 route miles of long-haul fiber and more than 700 miles of fiber optic metro rings in 21 markets connecting markets in Michigan, Indiana, Illinois, Wisconsin and Ohio. The US Signal network provides on-off ramps comprised of major carrier hotel locations and incumbent telephone company central offices.

US Signal said its future plans for the region include expansions into Akron, Canton, Lima and
Springfield.
