Yea, a little late-notice, but I figured late, is better than never.
We're going to be down for, at most, 1-2hrs to address some performance concerns.
After this, we hope to be up 24/7 without further downtime.
This will be happening in a few hours, when our traffic dies down. (So we affect the least amount of users as possible.)
Again, sorry for the late notice.
