Is Slack Down?

Messages that you've already sent but haven't been delivered will be queued and delivered once Slack recovers. However, if you're mid-typing and the app crashes, the unsent message in the compose box may be lost. Slack's draft feature preserves most unsent messages, but it's not guaranteed during outages.

First, check your internet connection by loading another website. Then visit status.slack.com from your browser. If you can reach other sites but not Slack, and the status page confirms an incident, Slack is down. The Slack app will also display a yellow or red connection banner at the top of the window.

No, integrations that rely on Slack's API will fail during an outage. This includes bot messages, webhook deliveries, and notifications from tools like GitHub, PagerDuty, and Jira. Most integration platforms queue failed deliveries and retry them after Slack recovers.

Have a backup communication plan before outages happen. Email is the most reliable fallback. Some teams keep a secondary tool like Microsoft Teams or Discord available. For incident response, phone calls or SMS via tools like PagerDuty ensure critical alerts are never missed.

Slack offers a 99.99% uptime SLA for Enterprise Grid customers, with service credits if that threshold isn't met. Business+ and Pro plans do not have a formal SLA. Slack's historical uptime is generally very high, with most incidents being brief and partial.
