PSA: a mtr showing one host in the middle of the path with loss and then other hosts further down with no loss is NOT proof that there is loss in the middle. It's proof the router in the middle won't answer your pings. You're not getting any loss over the path.

similarly, if you're getting "loss" at the end of the path, that does NOT mean it's a network problem. It could be that your destination isn't answering your pings for another reason (load, whatever); and if it is a network problem it can be another path than the mtr shows

anyway networks are more complicated than just looking at MTR and saying "ah, yes, here's your problem" and that's why there are people who do network specifically. Thank you for your attention.

@wxcafe But what if they really want it to be a network problem?
