Slack reports: All systems operational (“No active incidents reported”)

from Slack's own status page, checked Sep 23, 2026, 8:47 AM UTC
Our probes and Slack's own status page agree: both show Slack as reachable right now.

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.

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.

Somewhere else or not sure: 0 people in the last 5 minutes

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.

Monitor your own site the same way

This page shows what we see when we check this service, using the same ten regions, for a site you run. RealUptime Monitor watches your own servers from inside your network, and it starts free.

Tell me when this goes down

Get told when we measure this

We will tell you when our probes stop reaching Slack, and again when they can reach it again. That is our own measurement from ten regions, not Slack's status page. No account, no card.

Delivery channel

Double opt-in: nothing is sent until you click the link in the confirmation email. One email when a measured outage opens, one when it closes, and a one-click unsubscribe in every one. We do not send anything else to this address.

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. See how the badge works for every window and the honesty rules behind it.

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.

RealUptime is not affiliated with Slack; the name identifies what we measured, and nothing here speaks for Slack's own team. We send a single web request to Slack from 10 regions on our own schedule and time the response. We do not see inside Slack's systems, do not use an account or real transaction, and are not the same signal Slack's own team has access to. Treat this as one external data point, not a verdict. At least one endpoint we check for Slack is a real functional API call (marked “functional” above), not just a landing page, so a clean read there is a stronger signal than reachability alone, though it still does not cover every feature of the service.
