Measuring packet loss and Latency Between eastern Europe and north america

Mon Mar 30 20:16:48 UTC 2020

Don’t forget you can use any port/protocol for MTR and traceroute, which is
basically all the fancy apps will do, just automatically.

$ mtr -T -P 443  den01.example.com

This will send 443 tcp syn packets that should bypass icmp filtering or
rate limiting. Note this does not help if icmp responses are rate limited
at intermediate hops, but then again, nothing would.

As always, our good friend MANuel is here to help:
