DNS is one of those things that is easy to do yet hard to do right.
On the low end someone could run nsd/bind/powerdns on a vm from linode and one from prgmr and be 80% of the way there. That extra 20% involves getting your own IP space for anycast, proper instrumentation, BGP, probably colocation around the world, and making that all work together. If someone is going to go to all that trouble they darn well better be charging for it if you want to be able to depend on it.
- AxisOfEval 14y agoHmmm... Thanks. That clears it :o). But at the same time, I have rarely seen players who charge (and some of them quite a lot) advertise or talk about their anycast capabilities.
