AboveNet Announces Ethernet eXchange Hub Service

CENX and Equinix carrier customers will have first access to AboveNet's hub service in top metro markets

WHITE PLAINS, New York, November 2, 2010 - AboveNet, Inc. (NYSE: ABVT), a leading provider of high bandwidth
connectivity solutions, today announced the Ethernet eXchange Hub service
optimized to provide carriers with next-generation high bandwidth
connectivity. The new service will be available first to customers operating
in select CENX and Equinix Carrier Ethernet Exchanges.

The eXchange Hub service acts as the hub or central connectivity port in
the carrier exchange. Carriers can then leverage AboveNet's network for
Ethernet connectivity to key enterprise locations, carrier hotels and data
centers. With pre-positioned hub capability and a simplified provisioning
process, the carrier will get cost-effective, scalable, high bandwidth
connectivity to meet their business needs.

Key service features include:

    - high-performance Ethernet services with bandwidth levels from 100Mbps
      to 5Gbps.
    - competitive access pricing.
    - aggregated hand-off to the carrier at pre-defined exchange locations.
    - fiber-centric delivery with no space or power needs at service
      end-points.
    - ease of provisioning at pre-configured, existing hub locations.
    - capability to easily add more sites to meet carrier needs.

AboveNet already has existing strategic relationships with CENX and
Equinix that expand its reach to carrier exchange tenants in global markets
including Chicago, London, New York, Virginia and San Francisco. The eXchange
Hub service is a key addition to the Ethernet solutions portfolio available
to carriers who in turn can extend the business benefits of AboveNet's
high-performance Ethernet network to their own customers.

"AboveNet's expansive network footprint connects to business-critical
locations in the top U.S. and European metros. CENX members are already able
to reach more than 15 million Ethernet Service Locations (ESLs) via our
Carrier Ethernet Exchanges and this new connection provides our members
additional access to AboveNet's next-generation Ethernet services and
connectivity to the top global markets over a cost-effective, high bandwidth
network," said Eric Gillenwater, senior vice president, worldwide development
for CENX.

"Equinix is helping carriers quickly and easily connect, expand service
availability and speed their time to revenue in new markets," said Jim Poole,
general manager of Global Networks, Mobility and Content for Equinix. "We are
excited to partner with AboveNet, and welcome them to the growing list of
participants to the Equinix Carrier Ethernet Exchange."

AboveNet expects the eXchange Hub service to be available in the first
quarter of 2011. The full existing suite of services is currently available
to carriers in the leading Ethernet Exchanges.
