Received this from my hosts. As usual, little or no warning. On Friday, March, 23 we will be exchanging two of our main gateway servers with new and improved hardware. We will begin this planned maintenance at 10amCST and the expected downtime may range from 30 to 60 minutes. During this time your website, email, and other related services may not work. The purpose of exchanging this hardware is to offer better reliability, redundancy, and faster connection speeds to all services.
