Investigating intermittent failures

All Clear: In the course of resolving the telemetry issue and the downstream database issue, we uncovered a capacity issue in our ability to serve files to you. We right-quick addressed that, and Slack should be snappy and well. Sorry for the bumpy ride!

All users briefly disconnected and some slow to reconnect

We've further evaluated what happened a few minutes ago and have determined that all users connected to Slack were briefly disconnected. Some were able to reconnect almost immediately and others unfortunately had to wait for DNS caches to expire after five minutes before they were able to reconnect. We believe service is completely restored and are continuing to monitor the situation.

We unfortunately deployed a JavaScript bug that caused Slack web clients to fail before loading fully. This bug has been fixed and our pre-deploy safety features are being examined to prevent similar situations in the future.
