[logan_at_logan ~]$ ping 72.21.221.118
PING 72.21.221.118 (72.21.221.118) 56(84) bytes of data.
64 bytes from 72.21.221.118: icmp_seq=1 ttl=58 time=325 ms
64 bytes from 72.21.221.118: icmp_seq=2 ttl=58 time=315 ms

Saving around 60 ms on average is always an added benefit. I believe that
Orange can provide around 90-120 ms latency to the US. I saw it on an
Orange business line back in 2007.

At least, we can make it hard for them not to consider Mauritius :)
