Oh, the reason for my packet loss has been acknowledged by RR (after I practically spammed them with connection logs) as a problem
in the area, although when I called at first they said noone else is experiencing problems. I think they just acknowledged it as an
area problem so they could say they're working on it and get me off their backs :/ It's been almost 2 months and I still have an
open trouble ticket, though the frequency of this problem reduced somewhat. There isn't really anything I can do about it (according
to them).
As for that Wiki, I think it would be a most interesting reading! Warren: How about it?
