Hi Lars,
You should check out
https://ring.nlnog.net/ by contributing resources yourself you also get access to a wide array of machines from all across the world you can use to turn traceroutes and pings.
Some wrappers have already been made to run commands against multiple machines at the same time (
https://ring.nlnog.net/toolbox/), you'll have SSH access to run any commands you want and there is an API to find the probes if you want to automate it all.
I encourage anyone and everyone to join. The more networks the better!
Brendan
