How would they do that? does the data come BACK down the line?
There are millions of nodes on the backbone of the internet. Pretend that your connection to HTC goes through nodes 12,13,14,15,16,17,18,19,20. If the line connecting nodes 14 and 15 breaks it will be rerouted from 14 to 20 by going through node 28 first then to 18.19.20. It's all automatic in most cases, but it does take time, even a second to switch you will cause a disconnect from the game while you would never notice it while surfing the net (if page took a second longer to load would you notice?)
Of course this is a very simple way to explain "the internet" but it give you a basic idea of how it works. Now had the OP logged onto the boards and found 300-400 other post complaining about not being able to stay connected to the game that afternoon then it might be something HTC would have to check to make sure their servers aren't dropping EVERYONE then rebooting or something.
The internet is like driving to work. Everyday its the same old 40 minute ride, but then some bozo drops his coffee and slams into someone else whose doing her make-up and the next thing you know your being rerouted through the worst neighborhoods in your area dodging bullets and packs of wild dogs and it takes you 80 minutes to get to work if you even get there !
