Not sure, but it looks like the problem has been solved. Everyone: clear your caches.
jje: Are you sure it was per-filesystem and not per-IP? From what I can tell, there was no corruption.
Siddhant: maybe cURL maintains a cache? Try wget. All I know is that I'm getting your domain fine from here.
Maybe try accessing from a proxy to confirm your issue.
Uhm... what? They want me to register my nameservers with them? The Internet is based on a decentralized model.
What exactly would registering the nameservers entail? It is possible for you to use an alternate source for DNS?
Apologies; MySQL's Connector/NET wasn't installed at that point. I've installed it now. Does your script work properly now? mysql.data.dll is now installed in the GAC.
