If you don’t know, after you purchase a domain and before a site is in place there is a “parker” page which usually notifies visitors that the domain is not available and a site should be up soon–and shows ads for the registrar.  Leo Laporte (accidentally) let his twitlive.tv domain expire and after re-purchasing it, shows this message.

Oops. There may be an issue with the URL Forwarding service for this
domain, in which case our technical staff is currently working the situation. Otherwise,
this domain is currently under construction and will be back online soon.

This has to be the best message ever! I love the “otherwise” statement.
