We'll be going down around 11:30am UTC time / 4:30am Pacific for regular maintenance.
There is no large database restore or repair planned, so this should be well within the normal maintenance window.
We have made some progress on optimizations that should help performance.
The hope is to clean up the various character loading and gameplay issues.
EDIT: Servers are back online as of 9:10am Pacific.
It all seems to be connected. It lags the fast travel, garages, login, switching characters etc.
Might be some server "automated task" that runs once every hour for up to 15 minutes each time.
I'm slowly getting it narrowed down. How often, how long each time in my previous post.
