We have some maintenance scheduled for Wednesday, 21 September, 00:30-03:00 UTC. Read details on this Meta post: meta.stackexchange.com/q/382…

And that work is done. Thanks for being patient!

This work is starting now... Stack Exchange Data Explorer will be briefly unavailable.

We're going to be doing some database patching for Stack Exchange Data Explorer (SEDE - data.stackexchange.com), starting in about 15 minutes. SEDE will go offline briefly, but we promise we'll be quick about the disruption.

This maintenance is all done! Sorry for the interruption.

This is all done! Everything went smoothly & quickly! That's all for tonight!

Took a little bit longer than we planned, but this work is now complete.

Stack Overflow and the Stack Exchange networks have resumed normal operation.

Our CDN @CloudFlare is having issues in India at the moment. Apologies whilst they work towards resolving this.

We are beginning our test of Stack Overflow behind CloudFlare in just a few moments. xitter.cf/StackStatus/status/624…
