Is your database site down, or is it troubles at this end?
Ah, it's my stupid ISPs proxy. Doesn't allow underscores in URLs. How dumb of them.
Turns out from reading the documentation for the Squid proxy/cache that it doesn't allow underscores in domain names because they violate the standards documents. There could be other who are unable to view the site because of this as well.
