EUNetwork's New Paris/Milano Route
The well respected wide area network carrier has lit a new, shorter path connecting Milano and Paris data centers. While I believe you should never limit yourself to one vendor, EUNetworks is a very safe choice because it does the fundamentals well and is commercially flexible. The new route spans 1057 kilometers. EU did not provide a latency estimate, but it takes roughly 5.1 microseconds to traverse a kilometer. So multiply by 1057*2 and the RTD is approximately 10 ms. One diversity edge is that the route avoids Lyon. I recommend network planners consider to further diversity their network portfolio and reduce risk as a financail analysts might say.
