@kentfredric What is the "action item" for this issue report?

[kentfredric]

If your providers are looking for routing data to help shorten their route to end users, this dump is imagined to be potentially of use for them. (ie: if they have a way to peer directly with level3 instead of cogentco, they can eliminate a dozen or so hops)

[wbraswell]

So I should send a copy of this to my hosting company?

[kentfredric]

Well, it depends if they're asking for this. Its not always useful on its own, but it can be helpful in diagnosing slow points. Hence, this ticket is more a "dumping ground" in case anyone else has tcp induced latency.

Because just one person out here on the edge in an internet backwaters is seldom cause to invest in country-specific acceleration. But if you have multiple people who have long routes, having data to find common problems amongst can be helpful in solving problems.

But there's no "yes/no" here, only "it depends".

[wbraswell]

I will mark this issue as closed, we can reopen it or create a new issue if anyone else has any connectivity problems.
