You don't need anycast DNS for 30k users. Stay away from anycast unless you really, really, really know what you're doing. DNS is also TCP and no commodity DNS software environment implements an anycast TCP stack, only the normal unicast stack. Route splitting shows up in the most unexpected places and it won't just give you a bad day, it'll give you a bad month with intractable and seemingly (but not really) intermittent problems that are challenging to nail down.
