What UpButler measured

API edge is answeringHTTP 401 · 132 ms

One request without credentials to api.twilio.com every two minutes, from eu-central (one location, not a global view). An answer (the expected "not authenticated") shows the edge, TLS and routing work. It does not prove that authenticated calls succeed. The probe is for Twilio as a whole, not for Twilio Voice specifically.

Tell your outage from Twilio's

Declare that your project depends on Twilio Voice. When one of your monitors fails while Twilio has an incident that began around the same time, UpButler tags your incident "likely upstream" with their incident linked, says so in the alert and the AI report, and tells your on-call agent not to change code.

npx upbutler init finds the dependency from your env var names and packages. The catalog, dependencies and upstream-aware incidents are on every plan, including Free.

Questions

Is Twilio Voice down right now?
No. As of 2026-10-10 07:20 UTC, Twilio Voice is up. This page reads the status again every 2 minutes.
Where does this status come from?
From Twilio's own status page API at https://status.twilio.com. UpButler reads it once for everyone (not once per visitor) every 2 minutes with conditional requests, and shows it unchanged: incident titles and component names are Twilio's words. Their page covers more than this page shows; it is narrowed to the parts that concern Twilio Voice.
What does UpButler's own Twilio check prove?
Every two minutes UpButler sends one request without credentials to the Twilio API edge (api.twilio.com) from eu-central. Any answer from the edge, usually HTTP 401, shows that DNS, TLS and routing work from there. It does not prove that authenticated requests succeed, and it is one location, not a global view. It is most useful when it fails before their status page changes; the page then says so.
Can I get an alert when Twilio Voice goes down?
Yes, without an account: enter your email on this page, confirm the link we send, and you get one email when Twilio reports an incident that affects Twilio Voice and one when it is over. There is also an RSS feed at https://upbutler.com/status/twilio/feed.rss. Teams on UpButler can route the same alert to Slack, Teams or a webhook.
How can my agent or app check Twilio Voice status?
Fetch https://upbutler.com/status/twilio/voice/status.agent.json: a small JSON document with a verdict (proceed, retry, fallback or pause) and retryAfterSec. No key is needed. The same answer is an MCP tool, upstream_status {"service":"twilio","component":"voice"}, on https://upbutler.com/mcp/public.
How do I know whether an outage is mine or Twilio's?
Add "twilio" to the dependencies of your UpButler workspace. When one of your monitors fails while Twilio has an incident that began around the same time, your incident is tagged "likely upstream" with their incident linked, and your on-call agent is told not to change code.
