It worked for me the first three days, but now I am not able to get there. I'm getting timeouts. This is happening at the name resolution step, so the webserver itself is probably fine, but nonetheless, I am unable to access the site, since I don't have its IP address memorized.

Is this a known problem today, or is my ISP's domain server having issues? (Other domains I've tried seem to resolve fine, including the one for the interview...)
