I'm tired of having domains that don't do anything useful.
I have a DNS server which is up ~98%. All I really want is enough secondaries to make it reliable, but the problem is my primary is on dynamic IP.
I've written some software which allows updates over SSH to a DJBDNS zone file, which would allow someone to provide the service I require... but who can you phone at 4am? (No it isn't urgent, but then it has been "not urgent" for the last six months)
So I've cheated and used xtremeweb.de for full primary. It seems very slick.
Meanwhile I'll poke about on ns2exchange.com.
