Update: This maintenance seems to be complete as Guk and Sebilis players have been able to login for almost an hour now.
Daybreak Games‘ migration of EQ2 servers to EnterpriseDB continues with the Guk, Sebilis, and the StationCash Marketplace servers undergoing their upgrades tomorrow. This is not new hardware, but a substantial software change that will result in better performance and open the door for new functionality such as Cross-Server Dungeon Finder. The new software is also a tremendous cost savings over existing systems which you can read from this article way back in 2007. Good things come to those who wait?
From the EQ2 Forums:
The Guk server, the Sebilis server and the Marketplace for ALL servers will be unavailable for approximately 12 hours, starting at 2:00AM PDT.
Soe status says guk is up, so I figured I would log in. Server still locked despite the status showing green to the left and up at soe.com status. I guess their data feeds are not working right.
Server can be “up” but login servers aren’t allowing connections to it because it’s not ready. I’ve asked many times for the login server data to no avail.
