I had some trouble initially; my browser had cached the old IP, and was unable to realize that it should stop using the old address, and do a new lookup. But restarting the browser solved this problem; no problems since.
Note that if you had any problems on Friday night (or Saturday morning for you Euros)
that was probably me. I did some maintenance stuff then, which turned out to take longer than I expected. During that time the ranch was unusable, you would've gotten the "ranch is down while we perform maintenance" message - and no new data available until the maintenance was done (an hour or so later). So if that's what you mean, that problem is accounted for, and won't recur. If you're talking about other instances of slow response but without the maintenance message - well, dunno about that.
