Announcement of Experiments

Short Disclaimer: I frequently use the PEERING testbed myself, so I'm 
genuinely interested in where and why people draw the boundary of what's 
fine and what's not.

Iirc., the route collectors see a (drastically varying) number of 
poisoned routes (assuming everything within a loop is poisoning) in the 
DFZ at any point in time, affecting a (drastically varying) number of 
ASNs, prefixes, and paths. So why would you expect this experiment to be 
noticeable at all---I mean, compared to the day-to-day, "1% of the 
Internet is beyond broken and does Yolo things" noise? Very similar 
experiments have run in the past (e.g., [1] in 2018); did you notice them?

Would poisoning be tolerated if the PEERING testbed would be, e.g., some 
security-obsessed org that wants to avoid that your infrastructure 
touches any of its precious packets during the forwarding process? I 
guess what I want to figure out is: Is it the intention behind the 
poisoning experiments that bothers people or is the act of poisoning 

Kind regards,
