Deadfrog Access Troubles

What are the possible reasons that I can't access a certain server (specifically deadfrog.us)?

Whenever I try to access the site, I get a "can't find server" message. This has happened for the past two days, both times trying to access in early early morning (3am-6am). I hadn't visited the site for the bast few months, so I don't know if/when it actually started being a problem. I've already tried flushing/renewing the dns cache to no avail.

I'm using Firefox 2 in WinXP and my firewall is disabled. My connection is comcast.
thanks anyway in advance.

thanks for that. I considered that possibility, but with other people reporting that the server was indeed up, I assumed they might be telling me the truth and not being malicious pricks like yourself and that therefore, there might be a slim possibility the fault lay with me.

I really don't get your vitriol. I asked an honest question, in a neutral tone that blamed no one (in fact, I erred on the side of caution that it was something wrong on my end), provided relevant specs and expected at least the same level of respect as I had given. I don't know what I could have been thinking.
