It is a known problem with the internet. It is specific to certain areas and certain carriers and/or the exchange points to other carriers. You don't usually use your last mile ISP's network exclusively to get to any given service on the internet...that just isn't how it typically works. If the content you want is hosted on someone else's network there will be at least two ISP's involved--if the networks are in disparate enough areas there will be 3 or more ISP's involved.

And therein lies the problem. The people you are more likely to deal with initially when you call your provider will usually be looking only at your localized segments---say in/around South Carolina but not Virginia, NY/NJ, Chicago, Toronto, etc. along the entire path you take specifically to get to a particular server (an important side note: Blizzard West Coast from Arizona is NOT likely to be contact severs in both Japan and Montreal like this game does, so you can't compare this connection to that one). They also are not likely to be looking at the exchange to their third-party routing partner, something that is set up and maintained by a higher tiered team than the helpdesk guys. That is why you need to be pushing for a higher tier of support (tier3).

So your ISP isn't necessarily "lying" but you aren't getting the whole truth. There are countless cases of these issues occurring across multiple users in multiple regions for multiple web services spanning decades that have identified these very issues in route to servers that got things cleared up through their ISP's assistance. It is a known issue to check for that needs to be ruled out and if found resolved because no matter how stable and robust a server may be, an unstable route will cause problems. Period. It isn't hypothetical. It is essentially "Networking 101".

As for SE commenting on the matter...there really isn't anything more to say then they already have and do with the maintenance announcements. They have announced planned and completed infrastructure changes. They have announced issues,maintenance, recovery of third party partners they have agreements with for running the services (Sony and Ormuco). Anything outside of that is fourth party to them and as such they have no actionable agreements--our ISP's however have such agreements in place. SE has a thread for gathering information to contact those ISP's, but unless they can enter into a peering agreement there isn't much else they can do if that ISP chooses to not take action. That is where we come into play--we pay for their service and as such have more influence. But some may have to be more persistent in demanding they take action...mileage will vary, but they can be pushed into taking action in more cases than not.
