Over the last 7 days, Twilio has answered our automated checks with 100.00% availability and a typical response time of ~49 ms. According to Twilio's official status page, the most recent outage began 2026-08-21 04:13 UTC and lasted 36m (severity: degraded). It was reported as "Voice Call Failures Between a Subset of Twilio Phone Numbers and Multiple Networks in Japan".
Twilio provides programmable SMS, voice, and verification APIs used for messaging and one-time passcodes worldwide. Its incidents are usually confined to one channel or carrier route, so SMS delivery to one country slows while voice and the API are unaffected, and the visible effect is users not receiving login codes.

RedditIs Twilio down for everyone or just you?
Our automated checks are reaching Twilio normally right now, and it answered our last one in 37ms. That makes any trouble you are hitting more likely to be local to your connection, account or network than a full outage, which usually means you can fix it from your end.

Measured since 2026-08-12. Windows reaching further back are averaged over the 39 days we watched, not the full period. Counts our own checks. Days Twilio reported an incident are coloured in the timeline above but do not change this figure.
What to do if Twilio is down for just you
- Check whether delivery is delayed rather than failed, since messages are queued and usually arrive once a backlog clears.
- Test a second channel or recipient domain, because incidents are often limited to one carrier, region, or mailbox provider.
- Confirm you have not hit a rate or spend limit, which returns the same errors as an outage.
- Verify your webhook endpoint is still responding, as a receiving failure on your side mimics a provider problem.
