I'm regularly critical of the developers here and it seems to work completely fine. I got to go to Aether and play with my friends - we ran several instances and there was no issues, and even though I couldn't get back to Crystal last night before, I logged on before I had to leave for work this morning and got my character back to Crystal fine. It doesn't really seem like it's having "critical issues" to me just because they temporarily shut it off because it was getting slammed first thing in the morning. Once the novelty of going to check out other DCs wears off for people, I doubt the issue of not being able to go back to your home world will exist much at all either. Seems to me like they've done a good job.
