Dallas as well, can't connect.
I can also say the problem doesn't seem to be verizon (or their awful openwrt routers).
Here's the test:
1. Try to connect, examine connection, get the following:

Note: minimal packet loss, no issues save mysteriously can't get characters
2. This failed, let's try and log into a different DC, result is success, connecting to the server 199.91.189.74
3. Since this server is known to be good (disregarding any behind the scenes segmentation and access to server resources), let's add the following hostfile entry:
Code:
199.91.189.93 199.91.189.74
Note: this routes the first IP to the second
4. Attempt to log in to the original dc with the modification, result failure pointing at formerly succeeding IP

Conclusion:
Since we have an established connection transferring data in both cases with near identical throughput and one of them actually contacts the lobby server, we can make 3 assumptions:
1. That the TCP socket is created and that's it's exchanging data greater than a simple keepalive.
2. That the TCP connection is (or damn well better be) encrypted.
3. That VZ isn't dedicating resources to decrypting and analyzing the traffic of every call that goes through their routers.
Based on that reasoning, we can arrive at a reasonable conclusion:
There's either a downed server or a bad route (poisoned, lost, lb misonfigured etc) in the square DC in Montreal.
Edit: It is also possible that the information being streamed is causing redirection to an unavailable resource, or the resource is simply misconfigured and whichever service is powering this is throwing errors or returning invalid data. Once it hits the DC it's impossible to tell what precisely goes on without being inside of it, but we can in this case eliminate external factors.
