I’m running into this as well, and when I do a traceroute, i have one hop in the list that’s very strange. I’m in Austin, TX, and I connect to the Americas region.
But, hop 11 in my traceroute is to 137.221.65.122, which is a Blizzard server that, from what I can tell, seems to be in the Netherlands:
Hop 11 - 137.221.65.122 [ AVG: 673.8 MIN: 61.5 MAX: 1715.6 JITT: 669.0 LOSS: 0.0% COUNT: 664 ]
Why on earth is traffic for the US region, from a US address, being routed through Europe? Notice how high the round trip times are for that hop? I suspect that jump is the root of the issue (at least in my case).
Here’s the full route to 24.105.30.129:
