They seem to occur approximately 15-30 minutes before one of my skills completes training.
The Revelations II roll out seems to be going a bit less smoothly than anybody would like.
There was another database related issue early this afternoon (Pacific time) just as I was waiting for a skill to wrap up training.
The current message from CCP is:
We are having some database issues that are being addressed at this very moment. Server will be up again as fast as humanly possible.
Ouch. I feel sorry for the crew at CCP. Having problems at peak hour in front of a live studio audience is a very painful experience.
As for my own planning, I think I will either go for some longer duration skills or start trying to time them so that they don’t wrap up at prime time, GMT, which corresponds to early afternoon here on the left coast of the US.
(I have also come to appreciate the server status alerts that are built into EVEMon!)
