It seems to me that just trying port 22 if no contact can be made on 443 should be added to the requested features list. The reason being that probes could then work in places where policy allows 22. However I agree that the priority should be low considering the small number of cases this would fix and the likelihood that measurements would be affected by middle boxes as well.
I agree completely. The only question is, what are atlas probes supposed to measure, Internet infrastructure or "eyeball" perspective of the Internet? From what I see, the objective is somewhere in the middle with probes installed both in datacentres (measuring infrastructure) as well as at users homes (measuring eyeballs). If measuring the users experience is legitimate use case, then it shouldn't be problem to have some middleboxes on the way. -- Ondřej
