Yep, that is what the tracert is basically telling you. I haven't finished checking all of the battlegroup IP addresses, but the only one that ran cleanly is the Cyclone / Reckoning IP address at 12.129.209.68. Every other one so far hangs up somewhere down the line. Now, that might not mean that the server cannot be contacted. I'm not an expert with tracert results but I suspect that the tracert request is placed far down the list in terms of being processed by the servers, and as a result it will time out if the server is busy. The interesting thing in your tracert is that the hangup appears to happen on the hand-off from AT&T in the U.S. to the next server down the road. When you run the tracert to 12.129.209.68, it runs to completion, and keep in mind that the 12.129.209.68 address appears to be an AT&T address. The trace isn't perfect, but it looks acceptable. When you run a pathping test to the same address it completes, eventually, but it takes a long time and there are many hops from server to server with 100% losses. What you could to, temporarily, is try to join that battlegroup, just to see if the game connects and lets you play.
The fact that you ran the game on the first day it was loaded is interesting. Were you playing with the same battlegroup on that day? It also makes me think that you might have a firewall issue of some type inhibiting the game. Are you playing from an admin account or user account? You should be in a user account, and if so, its just possible that the firewall settings were not saved from the initial day, although I believe that they should have been. If you are in a user account, try a switch into the admin account and run the game and see what happens. You might want to try the Cyclone / Reckoning battlegroup just to see if you can join. If that does not work, my thought would be to navigate down to the firewall rules in your antivirus settings. This usually contains the antivirus firewall rules for all programs that pass through the firewall. When you are there, confirm that WOW is allowed to pass through the firewall. You could probably delete WOW from that list, close the antivirus windows for all of the settings and restart WOW. The firewall rule should either rebuild itself, or it might display a pop-up window looking for permission to allow the game to pass through the firewall. Have a look at the battlegroup and firewall to see what you can determine.
