Well, we do have more than 700 servers pinging everything we can, but in a very respectful manner (https://ipinfo.io/blog/probe-network-how-we-make-sure-our-da...). There is no special packet type or anything; it is just pings. Our volume is much much lower. We avoid doing anything that could annoy anyone. We just take the RTT and triangulate the IP location.
