FYI Amazon EC2 uses the non-routable network for
services local to each datacenter, or even to smaller subdivisions.  So
this is probably an extremely local Amazon time server.

That said, the Amazon part of the pool also contains servers not on that
subnet (I tried a DNS lookup from one of my own EC2 instances, and it
gave back routable IPs).
