XO Communications Announces Successful Launch of Concentric Hosting Services [September 27, 2004]

SAN JOSE, Calif., Sep 27, 2004 /PRNewswire-FirstCall via COMTEX/ -- XO Communications, Inc. (OTC Bulletin Board: XOCM.OB) today announced its small and medium sized business hosting brand, Concentric, has exceeded expectations since its launch in early June of this year and projects growing demand for these services.

"We are extremely pleased with our launch results," said Barbara Branaman, vice president and general manager of XO's hosting business unit. "Since re-launching the Concentric brand we've been focused on delivering reliable and cost effective hosting solutions to today's growing businesses. We are continually learning from our customers to ensure that we are servicing their unique needs now and in the future."

Several key solutions have been integrated into the Concentric hosting portfolio, including junk mail filtering to improve productivity, PayPal services to securely enable ecommerce, and a user friendly Web builder tool that enables businesses to easily create and design their own web presence. Results to date indicate that new customers are responding to these solutions, for instance:

* 75% of users are utilizing the integrated junk mail filtering, and 16%
of these users are taking advantage of the premium spam filtering
capabilities providing custom routing rules and attachment filtering
* 71% of the accounts purchased a domain name with many of these
customers also using domain aliasing allowing them to have multiple
domains per account
* 9% of accounts are using the integrated Web site creation tool -- Web
Builder -- to easily and quickly publish a web site

Over half of total emails received were filtered out by the junk mail filtering solution, indicating the usefulness of mail filtering to reduce the time required to delete unwanted emails. This filtering capability is expected to be an effective tool supporting business productivity. Concentric's easy to administer MySQL Databases, open-source script wizards and script handling tools are also proving to be popular tools with customers wanting to run applications on their sites.
