________________________________________________________________

In order to stay ahead the curve in technology, Wowrack has invested in a major network backbone upgrade. We will upgrade our current border routing and core routing equipments and provide a fully meshed network backbone topology. We have been planning this network upgrade for months and we are now finally ready to deploy the backbone upgrade. Our goal is to perform the upgrade with minimal if not zero impact on our network.

We will be performing hardware replacements and the upgrades on Tuesday the 25th of March , 2008 at 11 pm PDT. The maintenance window will end at Wednesday the 26th of March, 2008 at 2am PDT.

We are expecting the upgrade to have minor impact on network availability. If there are any outages, they should be brief and intermittent.

If you have any questions or concerns please address them to support[at@]wowrack.com or give us a call at 206-522-4402 and reference Wowrack Network Backbone Upgrade on 3/25/2008.

Thank you for your patience and understanding
