Bert is correct. My hosting company was supposed to move to a new datacenter on Friday night, resulting in a limited shutdown of my server. Apparently the job was harder or bigger than they expected, and the downtime has streached from a few hours to a few days. The site will be back, it is just a matter of when. Lots of customers who have servers with this company are upset, including myself. I’ll be looking into other hosting options when this current fiasco is resolved.
