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!
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 continuously monitor the status of slack.com and all its related services. If there are any interruptions in service, a note will be posted here. We will also post notices of scheduled downtime on this page.
Slack is a distributed platform and during any given incident it is rare for all Slack teams to be affected. For this reason, we report our uptime as an average derived from the number of affected users.
If you are experiencing problems connecting to Slack and do not see a notice posted, please email firstname.lastname@example.org. Follow us on Twitter for status updates.
