Outage alerts
CheckedGet Slack alerts when Slack goes down
Email alerts are free for up to 5 providers — Slack, Discord, and webhook delivery come with paid plans. Every alert is driven by Slack's official status feed, checked about every 10 minutes around the clock.
How to get Slack outage alerts
- Create your free account. Sign in with GitHub, Google, or an emailed link on the account page — no password, no card.
- Add Slack to your alerts. The 60-second onboarding asks which providers you rely on; pick Slack and free email alerts are live immediately (up to 5 providers).
- Want it in Slack or Discord? Paid plans add those channels plus raw webhooks: create a subscription, paste your webhook URL, and press Send test to prove the wiring in seconds. The alert setup guide walks through creating the webhook URL in each app.
Why it matters
Recent Slack incident activity
Slack recorded 100% uptime across 11 monitored days in the last 90 days. The official feed logged 25 incident entries in that window — exactly the changes subscribers hear about first.
What triggers Slack alerts
New incident
A fresh incident appeared on the official feed and started within the last 24 hours — historical backfills never alert.
Incident update
An open incident moved through its lifecycle (investigating → identified → monitoring …).
Incident resolved
An incident was resolved upstream, or disappeared from the provider's active feed.
Status change
The provider's overall status flipped (e.g. Operational → Partial outage).
Every delivery is claimed exactly once per event, retried once on failure, and recorded — overlapping check runs can never double-notify you. Alerts are driven by Slack's official status source: the official Slack status page remains the authoritative reference.

FAQ
Slack alert questions
Short answers to what alert subscribers ask most.
How fast will I know when Slack goes down?
OutageDeck checks Slack's official status feed about every 10 minutes, around the clock. The first check that sees a new incident or a status change fires your alert immediately, so email, Slack, Discord, and webhook subscribers typically know within minutes of the official feed changing.
Are Slack outage alerts free?
Yes — every account includes free email alerts for up to 5 providers, no card required. Paid plans add Slack, Discord, and webhook delivery, more subscriptions, and higher API quotas.
Which Slack events trigger an alert?
New incidents on the official feed (when they started within the last 24 hours), incident lifecycle changes, resolutions, and provider-level status changes. A subscription can watch your whole stack, only Slack, or specific Slack services.
Can I follow Slack status without an account?
Yes. The Slack RSS feed, the public JSON API, and the embeddable status badge are free with no sign-up — alerts exist so changes get pushed to you instead of you re-checking a page.
