Is Slack down for everyone or just me?
Right now down.now isn't seeing a broad Slack outage, so the problem is most likely local to you — your connection, your device, or the app itself. Try the app on mobile data instead of Wi-Fi, then restart the router. If reports start arriving from other people, this page flips to an outage within minutes.

The last recorded Slack incident was about 583 days ago, on 2025-02-26. The outage record below has the peak time, duration and what people reported.
How can I report a problem with Slack?
Use the report panel on this page and pick what's not working — it takes one tap and no account. Reports are anonymous, and they feed the live signal on this page immediately.
How does down.now know if Slack is down?
Down.Now watches two crowd signals for Slack — anonymous reports submitted here, and public social-media posts about it — and compares the live volume against what's normal for that hour of the day. A sustained spike above that baseline opens an incident, which is usually visible before an official confirmation. We measure what users report, not Slack's servers directly.
