How to check Slack’s status right now

• Go to Slack’s official status dashboard (it’s the source of truth for active incidents, maintenance, and historical logs). You can also subscribe to Atom/RSS updates there. (slack-status.com )
• Compare with user‑report aggregators (e.g., Downdetector) to gauge whether problems are widespread before Slack posts an incident; remember these rely on crowdsourced signals and can include local issues. (en.wikipedia.org )

If Slack seems down for you

• Try the web app and the desktop/mobile app to see if the problem is client‑specific.
• Hard‑refresh the workspace (or clear cache), then sign out/in.
• Check VPN, corporate firewall, or DNS filtering rules that might block Slack domains.
• Ask a colleague on a different network to confirm whether they see the same symptoms.
• If you’re an admin, monitor your org’s SSO/IdP and network health while you check the official Slack status page for any emerging incident.
