Downtime...
As some of you may have noticed, my Web host is having brain farts all over the place lately. None of my sites are very usable thanks to the poor quality of service and support on the part of my host right now. The problems seem to have begun around noon on Friday, September 19th. The symptoms include random HTTP 500 (internal server error) messages or extremely long load times.
I'm in the process of switching to a host that is more reliable. This new host is perhaps one of the best in the industry according to all of the reviews that I've read. Let's hope I have better luck there.
