I think I know why we get error 5006/2002

First of all, I'm assuming this is a server issue and your connection speed which indirectly affects your connection to the game.

Character data is partially stored on your computer, but the other half is stored on the servers. Trying to log into a server, requires your connection to retrieve said data. But since there are hundreds of people trying to log in at the same, the servers cannot handle processing all the data outputs at the same time. Resulting in an error of course. This may have something to do with cache data stored on our side which is retrieved by the server when we try to connect as sort of a certification maybe and simply put the servers cannot retrieve them in a specified time before kicking you out of the queue.
There has been a number of ways to get around this, one which is simple but seems to work; jumping data centers and changing back. But I don't think this works if you have a character already on the servers, since you are again trying to retrieve data. Though if you go to a empty server where you have no characters, I think that overwrites the previous cache with much less data on it. This method may or may not work in one try and may require some number of tries.

I don't think this can be technically 'fixed', since this is basically similar to a small scale ddos attack. They made preventative measures in-game for congestions by adding multiple instances and it works wonders. But when 100's or maybe even 1000's of IP's are trying to send information to the servers... that's when things starts to get frisky.

There is nothing that you can do to fix it, the login servers are down/crashed/overloaded. Anything that 'works' is just coincidence, this is a login server issue, there is nothing that any player can do. Flushing DNS cache, changing server, etc, are just coincidental. It will let you in sometimes, and not other times, even if you do none of these things, you will still have a small chance of 'getting in' (At least up until lately, when it seems that the login server has just crashed completely now, at least from what I see)

I got in fine just not over 20 min ago. It's still up. So your point is invalid.

Hardly.
This is still an ongoing problem. It's been on and off for me. Currently, I cannot get in. Now, stuck at queue. Your point is invalid.

[xXRaineXx]

I was stuck in queue for 30 min stuck at 1, kicked off, back into queue for 10min stuck at 44, cancel queue, re-click character, got in just fine. Like I said, this is both server-side and your own connection.

Yea, it's completely broken for so many of us.
I've been trying for hours... Nothing but 2002 all the time.

I think I have to agree with Titor. The first day I stuggled for hours with only 5006 and 2002.. but finally got in and played for around 30 minutes then logged out. The next day I got in got about 10 seconds, long enough to turn my character around, then I was DC'ed and could not get in the rest of the day. Not a thing I have tried seems to make a bit of difference.. including the red herring, changing of data centers. I suspect the server is not finished converting data. Indexing or something is still going on and the load on the servers is at a premium becaused of the new things to play with. I'm not going to be happy if all my subbed time runs out and I don't get to play.
