Update: The July 21st maintenance is complete. All systems are back to normal now.
There will be a service degradation for up to 20 minutes shortly after Sat, July 22, 2017 at 00:00 UTC (which is Fri, July 21 at 8pm in NYC). During that time job adverts will still display, job listings will still work, questions and answers will still display. However the site will be "read only," i.e. people won’t be able to add/edit new job listings, apply for jobs, post/edit questions/comments/answers, upvotes/reputations won’t change, etc. We don't love having to do this, but it is unavoidable and will prevent larger problems in the future. This should not be very disruptive since the site will still work for the majority of our users. Users that are affected will see a warning banner. We apologize for the inconvenience.
Here's a helpful timezone converter.
As described previously, we were running out of our "backup datacenter" in Colorado while maintenance was performed in our primary datacenter (known as "NY"). This is the "fail-back" to normal... or as we call it, this is our "success-over".
