Is Slack down right now?

No, it’s up.

Slack appears to be up and running normally.

checked responded in 22msHTTP 200

Over the last 7 days, Slack has answered our automated checks with 100.00% availability and a typical response time of ~25 ms. The most recent outage began 2026-08-20 13:07 UTC and lasted 15m (severity: degraded).

Slack is the default messaging platform for a large share of workplaces, with channels, calls, and a deep app ecosystem. Its clients hold a local cache, so an outage often begins as messages showing a retry indicator or file uploads failing while the workspace still appears to load normally.

Is Slack down for everyone or just you?

Our automated checks are reaching Slack normally right now, and it answered our last one in 22ms. That makes any trouble you are hitting more likely to be local to your connection, account or network than a full outage, which usually means you can fix it from your end.

Measured since 2026-08-12. Windows reaching further back are averaged over the 39 days we watched, not the full period. Counts our own checks. Days Slack reported an incident are coloured in the timeline above but do not change this figure.

What to do if Slack is down for just you

  • Check whether delivery is delayed rather than failed, since messages are queued and usually arrive once a backlog clears.
  • Test a second channel or recipient domain, because incidents are often limited to one carrier, region, or mailbox provider.
  • Confirm you have not hit a rate or spend limit, which returns the same errors as an outage.
  • Verify your webhook endpoint is still responding, as a receiving failure on your side mimics a provider problem.
