On August 16th, 2018 between 9:19 am PDT and 9:37 am PDT, Slack experienced an 18 minute outage, where all users could not use the Slack product.
A configuration change at 9:19 am PDT prevented our web infrastructure from communicating with a subset of our database infrastructure. This resulted in a complete loss of Slack functionality until the change was reverted at 9:37 am PDT. We called the all clear at 11:07 am PDT.
We are currently hard at work on scoping preventive measures to ensure this doesn't happen in the future.

While some folks are able to connect successfully once again, we're not out of the woods just yet. We hope to have some good news for you soon.
