WOTLK Client gets stuck at "Connecting", temporary fix below

Some hours ago I logged off for a few minutes, and then when I tried logging back in my client got stuck at "Connecting". I assumed there are server problems so I decided to give it some time. Now I tried logging in again and it got stuck at "Connecting" again, so I decided to do some tests. Here's what I did:

- Delete "Cache", "WTF", "Errors", and "Logs"
- Change realmlist from "set realmlist logon.warmane.com" to "set realmlist logon.molten-wow.com" (without commas)

I tried logging in now and I actually managed to log in. I asked around, no one else in my guild seems to have this problem.
Just for testing purposes, I changed the realmlsit back to "set realmlist logon.warmane.com" and tried logging in. It got me stuck at "Connecting" again. After changing back to "set realmlist logon.molten-wow.com" everything works fine.

I call this a temporary fix because it's so annoying to have my chat spammed every 2-3 seconds with a message telling me that I'm using the old realmlist and that I should change it to "logon.warmane.com" (which, as a reminder, gets me stuck at connecting).

Forums say other people are encountering the same issue. Can anyone confirm this? More importantly, can any Staff member tell us what's happening?
