I upgraded the server and increased the number or processes handling requests. As a result, the site seem much more stable now but traffic is also down. I’m going to make some further changes on the server either tonight or Monday.
Note: The CSS styling is a bit messed up; is this running some kind of lightweight web server? (I ran into this same problem when I was hacking away trying to get it to work offline)
It seems that the IP address of the server changed Tuesday night and I didn’t find out until last night. So I updated DNS and everything seems to be working this morning. It may take longer for the change to affect some people but they won’t be able to read this until that happens anyway.
