UPDATE (2218 UTC): Ok, we are in the process of rolling back. UPDATE (2130 UTC): This update isn't going as smoothly as I had hoped. We're going to give it 20 more minutes to debug and if we can't then we'll roll back to the previous configuration and reassess. UPDATE (2054 UTC): The site is live again, but very slow to respond. we are working out the kinks and should have things running smoothly again soon. UPDATE: we're going to take the site down again here in a minute for about half an hour. UPDATE: ...and we're back! UPDATE: I'm going to keep the site offline for a while longer, up to half an hour, just to make sure everything is ok before we come back up. will update at 1900 UTC if anything changes. Hey, had to take the site down for a minute. Will have it back up asap.
