Front door check counts and Twilio’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 Twilio 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.

    Endpoint checked

    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 Twilio product, region or your app worked.

How we count front door checks

Shorter 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.

Twilio says

Incident posts from Twilio’s status page, with its titles, impact levels and times. They say what Twilio 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 Twilio currently down?

Twilio's latest recorded status is Degraded. 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 Twilio last have an outage?

The most recent closed incident record began earlier today and spans 13h 16m. 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 Twilio?

No. CheckUpstream checks Twilio’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 Twilio 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 Twilio?

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.
