I just tested it from a Verizon DSL host and it worked.
You might want to consider reading RFC 2182 though, particularly the
part about geographically diverse nameservers.
Yeah, yeah, that is overrated. If my site goes dark and my DNS goes
down it doesn't really matter as the bandwidth and the web server
will also be down. Having a live DNS server in another part of the
country won't help if the access routers handling the traffic for the
T1 to the school is also down.
