Pings to 1984.is: From Palo Alto : round-trip min/avg/max/stddev = 183.514/184.035/184.898/0.466 ms From Amsterdam : round-trip min/avg/max = 36/37/39 ms From London : round-trip min/avg/max = 48/48/50 ms Obviously this can vary quite a bit depending on what peering you have at your disposal. For reference, from Palo Alto to London: round-trip min/avg/max/stddev = 156.236/156.921/158.271/0.834 ms For latency, I would choose NY/NJ or similar if you really want one location to serve both EU and US; Though this isn't ideal, it does lower the latency to West Coast US quite a bit. From San Jose to Newark : min/avg/max/stddev = 73.462/73.547/73.660/0.078 ms From London to Newark : min/avg/max/stddev = 72.836/74.323/75.600/1.200 ms

From your pings, it seems pretty likely that traffic from your Palo Alto location is going through europe to get to iceland, most likely through London. The submarine cable map shows one cable going west to greenland and then Canada, one that goes to northern England, and two to Denmark. The Canadian landing isn't very close to any other transatlantic cables, so it may not be very well connected (land connectivity is much harder to map though). Anyway, making location decisions based on assuming internet distance is similar to physical distance is kind of silly. There are many physically adjacent countries that don't have direct interconnects, it's pretty common for traffic to exchange through somewhere much farther away than the ultimate destination: many south american countries exchange traffic in Miami.

  You’re right that it’s silly - from an IP topology layer Iceland might as well be mars. There was a bunch of news several years ago that Iceland was awesome because geothermal but a) there are other grids that are just as good if not better (Norway for ex) and b) doesn’t erase the otherwise terrible trade offs in network and dc options that are available.

Are these all your employer's servers? Or is there a service you utilized?
