Square, your NA/EU data centre has serious issues...

Please take you routing crap elsewhere, it is not, nor ever was relevant to my thread.

It's not only relevant, it's the cause of the issues you're seeing. Plain and simple. Route paths are the most important aspect in networking. It gives you a reference point to an otherwise impossible to pin down issue. It's your compass when you're lost in the networking world.

You're frustrated. I get it. I also sympathize with you. Techs at ISP companies aren't known for their intellect. They only have visibility into their own infrastructure (just like Square and EVERY other telecomms company).

I'll break it down:

You are in LA (CLIENT) and you are getting on a plane to NY (HOST). It should be a quick trip with minimal layovers (HOPS). However, there is a storm (PORT OVERLOADING) and you are delayed. You then have a layover in Chicago (BOTTLENECKING) increasing your time to NY (HOST). This adds time onto your total flight time (LATENCY/PACKETS). You took longer to get to NY (HOST) and now you've missed the grand gala inauguration ball (MD5 ERRORS/DESYNCHRONIZATION TO HOST) but you made it, you're just late (RUBBERBANDING/RUSH OF DATA).

The internet isn't a point A to point B. Ever. You have to route though major hubs to get to your destination. If the hub is having problems, you have problems. Though it may appear the issue is with Square, they do NOT own the hubs and as thus, cannot provide maintenance or support on them. Does this make it Square's fault? No, it doesn't. They are just the end point. Only by changing flight paths (MORE RACKS) can they service the amount of people passing through their terminals (SERVER/HOST).

Though this isn't the best analogy, it does show how the internet works and how many companies are involved and the MILLIONS of miles of copper/fiber you have to go through to get data I/O.

You're blaming the wrong people.

Actually the cause is entirely the game/data server. This is an email I got from SE support today:
