Pop, If it were a firewall problem I'd be having trouble with at least one or two other sites, but I'm not. My ISP is Qwest, which covers most of this part of the country. Seems to me that if Qwest were the problem there's be a deafening outcry. If I were having trouble with other sites I'd spend time tracking down the problem, but it's a cost/benefit consideration: I have a lot of other stuff that needs doing.
Well, it turns out that there is a problem with the DNS for jeremypayne.net that may affect some regions and not others. One of the domain's nameservers isn't responding to DNS requests. I've attached a screen grab of the DNS report I just ran on the domain that shows the problem.
