Guild Wars appears to be having odd network issues with some users.
Quote:
| We are currently experiencing a service outage for those players in locations served by the Los Angeles Data Center. Investigation indicates that this is an external problem located on an Internet backbone. An estimated time for service resumption is not yet known. We will post more information as it becomes available. We apologize for this interruption. |
This is a guess on my part but may be why your having issues and Anet statement about "An estimated time for service resumption is not yet known."
Level 3 and Cognet are in a contract spat. They are companies that provide the backbone of the Internet. If you are on a Level 3 network (or your ISP is) you will NOT be able to easily / quickly access resources on Cognet and vice versus.
Guess - anet has part of there network on either of these (or both) this may explain a few things.

(edit) - Found the this support article, it has a program for testing your network connection.

Something I found intresting, on the 3rd address that it checks to see if it can connect, it ends up on level 3's network.
