Ctrl+F5 (Windows) or Cmd+Shift+R (Mac)ipconfig /flushdns (Windows) or sudo dscacheutil -flushcache (Mac)1.1.1.1 (Cloudflare) or 8.8.8.8 (Google)As of 2026-08-28 18:17:25 UTC, our server probe returned HTTP 200 (ok) in 241ms — Slack is up and reachable.
If our server reaches Slack but you can't, the problem is usually on your side: a stale DNS cache, a VPN or proxy, your ISP blocking the site, or a browser issue. Try a hard refresh, clear your cache, or load the site on another network. If our server can't reach it either, it's a genuine outage on Slack's side.
That's exactly what this page answers — we probe Slack from our own server, not from your browser. Up = it's just you. Down or erroring = it's affecting everyone.
