Yes and no.

Yes in the sense that in all the times that I have been trying to log in the beginning, I haven't run into a single server full error, although I DID run into a few 90000 errors as well as 3102s after the first short but successful login.. Later on in the day I was able to log on stay on longer then I have been since Saturday. During this log in I had to be put into a queue of 9.

No because there are still some random errors floating about including fps/lag issues according to some and including me. Since these are completely separate issues, I have hope that this will be fixed later on especially since the lack of the 3102 errors happened right after they made their last lodestone update, stating that they had taken care of the problem. And whatever they did was a few hours after their huge maintenance and they didn't have to take down the servers.
