This is changing.

Since thunrsday, the ping (time it takes for a packet to be sent and
an acknowledgement received) between our fuchsia server (ENS network)
and various machines in Montevideo (www.universidad.edu.uy and
www.fing.edu.uy) has dropped from 300ms to 150ms.

We get different timings from our green server (ENS netwoek, CMLA
subnet), even if the packets follow the exact same route; I can't
understand why.

But the routing is changing. Now packets from Cachan to Japan jump
directly from Amsterdam to Tokyo without taking the long western road
(via USA) they used last week.
