SiteFinder was a whole other beast. It affected all Verisign run TLD's.
It was unavoidable, even if you ran your own DNS server, you still had to talk to Verisign's root for their TLD's.
In this new case, if it's only your ISP doing it, and if you know what you're doing, you can get around it.
If you don't know what you're doing, you probably don't care either way.
