A couple weeks ago, Crygil posted an update on the instance creations issues in plaguing servers in World of Warcraft. In that post, Crygil said Blizzard was optimizing its infrastructure to help ease the problem, and more than 40 percent of of North American servers had been optimized at the time.

Well, Crygil just added more servers to the optimization list. You can view the updated list after the jump. Remember, as Crygil said in the thread, "If your realm is not listed there, then it has yet to be reconfigured and we are working toward getting there."
