I usually stay up 24x7 when I have a coder working on the site and check everything when he's done. I was up the night before and didn't have it in me last night so missed that people with normal accounts had problems. Ideally a dev environment would be best. This might be something I setup once I'm back to APUG full time, will be no easy task though since there are several apps and countless modifications, disk space is an issue as well..
