Is Slack down?
Operationalchecked moments ago
We reached Slack from all 10 regions we check.
As of Oct 5, 2026, 8:16 PM UTC, Slack answered RealUptime's probes in all 10 regions that returned a reading.
No outage recorded in the 58 days we have measured Slack (since Aug 8, 2026).

Slack reports: All systems operational (“No active incidents reported”)
This is Slack's own claim about their service, shown separately from what we measured. We never change our own numbers based on what a vendor reports, and this reading never changes theirs. Read both.
Slack response time, by region
Is it Slack, or is it you?
Watching an outage above does not tell you whether your own connection or site is also having a problem. Enter your own URL for one live check, right now, no signup. This checks the site you enter, not Slack -- it cannot diagnose Slack's own systems.
What we measured, function by function
Slack answers on more than one surface, and they can fail apart. Each row is one surface, checked from the same regions. The verdict above follows the api row, because that is the surface we treat as this service's own; a failure on any other row is a partial outage, not a full one.

These are unverified reports from people using Slack, counted separately from what our own probes measure. Anyone can file one, no account is needed, and the region on a report is chosen by the person filing it. We never open, extend or close an outage in our record based on report volume: only our own measurements do that. We have not received any reports for Slack yet, which is not evidence that nothing is wrong.
Recent outages
No outages on record yet for Slack.
measured entries are our own probes' readings; declared entries are the vendor's. How this check works
We have been measuring Slack since August 8, 2026. We show nothing from before that date, and we never add an outage we did not observe ourselves, from any source.

Live, from this page's own readings.[](https://realuptime.io/outages/slack)<a href="https://realuptime.io/outages/slack"><img src="https://realuptime.io/outages/slack/badge.svg?days=30" alt="Slack uptime measured by RealUptime"></a>The badge shows the share of our probes that succeeded over the last 30 days, and the window is printed on it so the number always says what period it covers. If our readings go stale it says stale, and if we have no readings it says so: it will not show green on data we cannot vouch for. Free, no account, and it links back here.

What Slack's SLA implies, from our measurement
At or above your target
We measured none of downtime for Slack over the last 30 days, which is 100% uptime by our reading. A 99.9% target allows 43 minutes over that period.
By our measurement there is no shortfall to claim for this period.
This is computed from our own probe measurements, not from Slack's SLA instrumentation. Their contract is normally measured against their own systems, with their own exclusions and a claim window, so their figure and ours will differ. Use this to start the conversation and ask for their number. It is not legal advice and it is not a determination of what you are owed.
