We are deploying a new Plesk server to replace Plesk4.
To avoid confusion, we will be naming this "west.lvcs.net"
The new server will feature new updated hardware, more memory, RAID, as well as the latest OS, Plesk, Apache, MySQL, and PHP versions.
We will provide more information when this has been completed.
At this point, we will be maintaining the existing Plesk5 and Plesk6 servers, however, we are seriously looking to setup a new server in Chicago that could potentially replace both of these machines.
