I'm investigating a complaint of poor performance from an end user accessing a site I help maintain.
I have these two mtr outputs to the end user, the first from the site:

How should I interpret those hops with MASSIVE packet loss? I'm inclined to think those hops have some sort of asymmetric routing going on and one of the paths is congested.
Could this cause any problem for the end user?
