Vendor reports Operational

Checked

Front door check counts and AssemblyAI’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 AssemblyAI endpoint and count the checks that got the answer it is documented to give.

  • Front door reachable in 2,878 of 2,878 checks with a clear answer, last 30 days, checked every 15 minutes from a single CheckUpstream location.

    1 more check gave no clear answer and is not counted.

    Endpoint checked

    First check in this window
    Latest clear answer

Checks 15 minutes apart cannot see disruptions shorter than that. A check that reached the front door does not show that every AssemblyAI product, region or your app worked.

How we count front door checks

AssemblyAI says

Incident posts from AssemblyAI’s status page, with its titles, impact levels and times. They say what AssemblyAI 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.

15

incidents AssemblyAI posted, last 180 days

Frequently Asked Questions

Is AssemblyAI currently down?

AssemblyAI'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 AssemblyAI last have an outage?

The most recent closed incident record began 10 days ago and spans 26 minutes. The vendor reported degraded performance. 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 AssemblyAI?

No. CheckUpstream checks AssemblyAI’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 AssemblyAI 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 AssemblyAI?

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.
