We’ll be performing some server maintenance on our primary SQL clusters between 9:00-10:00AM EDT (13:00-14:00 UTC) on July 14, 2018. We expect to be read-only less than an hour and in full maintenance mode only a few minutes.
For more details, see our post on meta.stackexchange. If we’re in maintenance and you can’t see that post, try again in a few minutes!
