They could remove the affected servers from Route 53 and point to some other region until the DDOS stopped. True, they'd have to use a small TTL and clients using a bad-behaving DNS might receive the wrong IP for a while, but depending on their SLA, that might be acceptable.

Would something like Anycast allow them to failover faster? I would imagine route propagation isn't instantaneous either, so I'm curious how big the difference would be.
