I'll chime in a little here.
Login queue: from what I've seen and can assume from the workings of the game so far, the login queue (handling you logging in, making a toon, and pulling a server list) is completely separate from the server. All server related functions (from requesting to log in, all the way to playing) are handled on another cluster. So all the login server really does is query the game server and receives this 1017 error. It cannot generate a queue because the login server has no idea when an opening occurs or even what capacity the server is running at. Shoddy coding to say the least, but this seems to be the way they coded their servers to work together.
New servers: not as hard as you'd think to implement. Most likely they have backup images of all types of game servers (login, servers, dungeon). This allows them to quickly repair a damaged or corrupted server, and in this case allows them to quickly take a server out of the box, image it, and force it into a cluster. They're also likely using virtual clustering and virtual servers, which allows them to take say 5 servers and virtually shard that cluster into 20 servers, or whatever numbers you'd like to use. That makes the baseline imaging of a new machine even easier given that the existing cluster can shift the virtual machines around as needed (or manually) to balance the load.
The "fix" here is simply that to add new hardware, usually you cannot have users online because a lot of these programs go crazy when hardware starts changing up (like plugging a new IDE drive into your computer while it is running in windows). So they schedule more than enough time to implement the changes start to finish (which is more guess work than actual science) and then go for it. The reason they chose Wednesday was to give themselves some prep time and to not disrupt the game during a US holiday. They understand a lot of people are put off by the fact that they cannot log in, but many more are enjoying their experience, and they don't want to close the doors on a big holiday. Imagine the backlash of that... like Battle.net's error 37 but over a 3-4 day weekend. It'd be the end of the world, at least on the internet.
Anyways, one more day. Good luck sweating it out! I hear exercise is a heck of a drug, try it or religion to ease your withdraw symptoms.
