![]() ![]() OK, so what can you do? Well, I hadn’t thought much about the issue, until seeing this by Restore Privacy. However, projecting actual routing and minimum rtt from Border Gateway Protocol (BGP) information is utterly nontrivial. Because those two ISPs don’t peer directly with each other.īottom line, given unknown routing and equipment latencies, it’s generally not feasible to triangulate using multiple rtt measurements. That’s much greater than the actual distance, which is ~15 m.Īlso, connections don’t always take the shortest path, because paths depend on peering agreements between ISPs: Two computers in the same city, but connected to the internet via different ISPs may route through a city hundreds of miles away. For example, the rtt to my LAN router is 0.3 msec, which implies a physical distance of 45 km (not 90 km, because ping is a round trip). There are delays from both processing and caching, and those delays are typically substantial, relative to transmission times. It also depends on the number of hops (routers and switches) between the probe and target. However, rtt doesn’t depend just on distance and transmission speed. And about 150 km/msec for electrons in copper wire. The speed of light in vacuum is 300 km/msec, and about 180 km/msec in fiber optic cable. Still, how can you verify that? Well, you can ping VPN servers, to get round-trip travel time (rtt). And if you’re connected through a VPN server, you can search for my location to see where Google considers it to be. But they just provide information from various geolocation databases, such as. OK, but how do users know whether VPN servers are located where providers claim? People commonly use such sites as, ipinfo.io, or. And it costs less than either IVPN or AirVPN. That’s basically every country on the planet. But HideMyAss (HMA) is mind-bogglingly huge, with over 700 servers in over 280 locations, in over 210 countries. AirVPN has appreciably more, with 216 servers in 35 cities in 19 countries. IVPN has 77 servers in 44 cities in 31 countries. However, choice of server locations remains a major issue for many users. On speed, torrent-friendliness, privacy and no-logging, edginess, price, technical elegance, multi-hop routing, customer support, and so on.
