Vendor record
Slack
Checked
Front door check counts and Slack’s own incident posts. Use them to investigate a dependency; neither confirms what happened in your app.
Front door checks
We send a request to a documented Slack endpoint and count the checks that got the answer it is documented to give.
Front door reachable in 2,879 of 2,879 checks with a clear answer, last 30 days, checked every 15 minutes from a single CheckUpstream location.

Checks 15 minutes apart cannot see disruptions shorter than that. A check that reached the front door does not show that every Slack product, region or your app worked.
How we count front door checksShorter disruptions
Our checks are 15 minutes apart, so they miss disruptions shorter than that. Datadog runs a separate outage tracker that may show disruptions our checks cannot see.
Independent outage detection for Slack: Datadog’s Updog(opens in a new tab)CheckUpstream is not affiliated with Datadog.
Slack says
Incident posts from Slack’s status page, with its titles, impact levels and times. They say what Slack chose to post, not what reached your app.
A closed record shows when our record closed. Some older records closed when a post left the status page, without a resolution post from the vendor.

Frequently Asked Questions
Is Slack currently down?
Slack's latest recorded status is Operational. Check the timestamp and linked source at the top of this page. A vendor status report does not establish whether your application was affected.
When did Slack last have an outage?
The most recent closed incident record began 4 days ago and spans 6h 21m. The vendor reported a partial outage. Closure may reflect a disappeared post or an expired tracking period; it does not confirm vendor or application recovery. Check the dated history and source links.
Does CheckUpstream publish an uptime percentage for Slack?
No. CheckUpstream checks Slack’s front door every 15 minutes and publishes how many checks reached it over the last 30 days, with the endpoint checked. Checks 15 minutes apart cannot see disruptions shorter than that. A percentage would claim more than the checks can show.
How do I monitor Slack in production?
Create your account, connect GitHub or GitLab and choose a public or private repository. Review the vendor matches and your alert settings. Available notification channels and history depend on your plan.
How does CheckUpstream track Slack?
This record separates vendor-reported incidents from independent checks. Sources and coverage vary by vendor: review the linked source, check time and measurement scope. Neither kind of evidence establishes SLA credit eligibility.
