As far as what to tell your ISP goes - we unfortunately can’t really currently give any concrete evidence apart from telling you that you should report the error en masse. The reason I can’t give exact specifics is because of how those tests are reporting. We just don’t have the data we usually use to point things out to people, which is why I’m having to be a bit more vague than I typically like with these.

Basically getting pressure on the problem from both ends lets us use a little more leverage if we end up working with them, or they may just find that something’s misconfigured. You’d want to tell them exactly what times of day you’re having problems and that most other players are able to connect normally, but there are a number of players in your specific state/ISP having this issue. You might even direct them to this thread.

We’ll continue checking it out, but to set proper expectations, we can never promise we will be able to fix a problem like this because we have to first discover if the problem is something we can even impact. This is why reports from the customers of the ISP are critical - they’ll have more tools they can use to try to reproduce the issue on their end as well. You may need to talk to a tier 2 or 3 to see if they can test connections to our servers while you can’t connect to have them look for the point of failure.

Also of note, those of us in the tech support forums don’t directly work with our ISP, so we basically just forward the information up once we have it, then our network folks look it over to see what can be done or what else we need.
