The textbook answer is to use anycast, which is how ISC (among others) provide redundancy for their F-root nameserver.
Sure, but I'm afraid I won't have anycast available for this project.
Failing that, you'd probably turn to simply having more than one server in any location and employing more mundane clustering and load-balancing techniques to share your DNS servers' I address(es) between several physical servers.
But even if I have multiple servers at one location, the location itself can fail (what happened i.e. for Wikipedia quite not so far ago, I think).
Is there anything "better" than relatively small TTL (+ some heartbeat reconfiguring zones), to be sure the site is still available for, say, European users (assuming European location totally failed)?
