As such, you typically only see it leveraged for simple services (e.g. DNS, NTP).I've been thinking about this for NTP. Wouldn't you end up with constant corrections with NTP and Anycast?
I am not a time geek, but the general and consistent advice I have heard from actual such geeks is, as you suspected, not to use anycast to distribute NTP service. I imagine that advice could be modified somewhat if you differentiate between NTP as used within a mesh of well-synchronised clocks and NTP as an occasional service for mobile clients that require only a loose sense of now. The latter seems like availability might be more important than stability over an extended period, so anycast might make sense there. Joe
