Twilio Status: How to Check If Twilio Is Down Right Now (2026)
Updated June 2026 · 7 min read · By API Status Check
Quick Answer: Check Twilio Status Now
Twilio is the backbone of communications for over 300,000 active accounts, powering SMS notifications, voice calls, WhatsApp messaging, and two-factor authentication for companies from startups to Fortune 500s. When Twilio goes down — even briefly — it means failed OTP codes, silent SMS alerts, and broken contact center operations. Knowing how to check Twilio status and diagnose the root cause can be the difference between a 5-minute fix and hours of customer-facing downtime.
Understanding Twilio's Status Page (status.twilio.com)
Twilio operates status.twilio.com — its official status page. Twilio organizes status by product and by region, because messaging reliability can vary significantly by geography and carrier route.
Programmable SMS
Core SMS sending and receiving via the Twilio API. Issues here affect message delivery for all SMS-based notifications, OTP codes, and marketing messages. Carrier-specific degradation is common and appears as partial outages.
Programmable Voice
Inbound and outbound voice calls via the Twilio API. Issues affect call quality, call setup success rates, and call recording. Typically more stable than SMS due to fewer carrier dependencies.
WhatsApp Business API
WhatsApp messaging through Twilio. Issues affect WhatsApp notifications and customer support conversations. Dependent on Meta's WhatsApp infrastructure in addition to Twilio's own systems.
Twilio Verify
OTP verification service (replaces manual OTP logic). When Verify is degraded, two-factor authentication and phone number verification flows fail for your users. High-impact for auth flows.
Twilio Flex
The Twilio contact center platform. Issues affect agent interfaces, routing, and supervisor dashboards. Flex issues can occur independently of underlying Voice and Messaging issues.
Twilio Console / APIs
The developer dashboard and management APIs. Issues affect account configuration, purchasing phone numbers, and viewing logs — but typically don't interrupt in-flight messages or calls.

Twilio's own status page organized by product and region. Updated by Twilio's engineering team during incidents. Can lag 10–20 minutes behind real outages, especially for carrier-specific issues.
Check status.twilio.com →API Status Check (Independent)
Third-party monitoring that continuously pings Twilio API endpoints and reports independently. Shows issues even if Twilio hasn't updated their own status page yet.
Check independent Twilio status →X / Twitter
Search 'Twilio down' or 'Twilio SMS not working' on X. Developers and ops engineers report delivery failures quickly. Especially useful for carrier-specific issues that Twilio's status page may not reflect.

Make a test SMS send via the Twilio API to a known good number. If you get an error code back (not just a queued status), it indicates an API-level issue.

Log in to console.twilio.com → Monitor → Logs → Errors. Look for error codes 30001-30099 (SMS delivery errors) or 13xxx (voice call errors) across recent messages to identify patterns.

Twilio error codes reveal whether the issue is on Twilio's infrastructure, the carrier network, or the recipient's device. This distinction matters for troubleshooting:
"Error 30001 — Queue overflow"Twilio's message queue is full. Often indicates a platform-level issue during high-traffic periods. Check status.twilio.com."Error 30003 — Unreachable destination handset"The recipient's phone is off or out of coverage. Not a Twilio outage — this is a carrier/device issue on the receiving end."Error 30005 — Unknown destination handset"The destination number doesn't exist or has been deactivated. Not a Twilio outage — check that the recipient number is valid."Error 30006 — Landline or unreachable carrier"The destination is a landline or non-SMS-capable number. Not an outage — SMS cannot be delivered to landlines."Error 30007 — Carrier violation"A carrier blocked the message due to content filtering or spam detection. Common with A2P SMS — check your message content and opt-in records."Error 30008 — Unknown error"An unspecified carrier error. Can indicate carrier congestion or routing issues. If widespread, check status.twilio.com for carrier-specific notices."HTTP 429 Too Many Requests"You've hit Twilio's rate limits for your account tier. Not an outage — reduce your sending rate or upgrade your account to a higher throughput tier.Twilio Outage History: What the Data Shows
Twilio is highly reliable for its core API infrastructure, but SMS delivery involves carrier networks outside Twilio's direct control — making true end-to-end uptime harder to guarantee:
The key distinction: Twilio can accept and queue your messages (API operational) while delivery to specific carriers fails. Always monitor both API response rates and end-to-end delivery rates in your own dashboards. Check our Twilio monitoring for current and historical uptime data.

If SMS Delivery Is Failing
- Check error codes in Twilio Console → Monitor → Logs
- Determine if it's Twilio-wide vs. carrier-specific (e.g., only AT&T numbers)
- For OTP: enable fallback voice call delivery via Twilio Verify
- For A2P SMS: check if your campaign is still registered and approved
- Consider email or push notification as a temporary fallback channel
- Alert your support team before users start creating tickets
If Voice Calls Are Failing
- Check the specific SIP error codes in your call logs
- Test with a different destination number to isolate the issue
- Check status.twilio.com for region-specific voice incidents
- For contact centers: enable a fallback PSTN trunk if configured
- Review your TwiML application for any recent changes that may have caused errors
Frequently Asked Questions
Where is the official Twilio status page?
Twilio's official status page is at status.twilio.com. It shows real-time status organized by product (SMS, Voice, WhatsApp, Verify, Flex, Segment) and by geographic region. You can subscribe to email, SMS, or webhook notifications for specific components you care about.
Why are Twilio texts not being delivered but the status page shows operational?
Twilio's status page reflects their own infrastructure. Carrier-side issues — where the mobile operators filtering or blocking messages — often don't appear on Twilio's status page. Check the specific error codes in your Twilio console (error 30007 = carrier violation, 30003 = unreachable handset). If you see widespread 30001 (queue overflow) errors, that's a Twilio platform issue worth escalating.
Does a Twilio outage affect my two-factor authentication?
Yes. If you're using Twilio's SMS for OTP/2FA and Twilio's SMS delivery is degraded, your users won't receive verification codes. Twilio Verify has some built-in retry logic, but full outages require a fallback strategy. Best practice: offer voice call delivery as a fallback, or use TOTP (authenticator apps) as a primary 2FA method.
What's the difference between Twilio being down vs. carrier issues?
Twilio's infrastructure (accepting API calls, queuing messages) is separate from carrier delivery networks. Twilio can report 'operational' while your messages fail to reach AT&T or T-Mobile subscribers due to carrier-side congestion or filtering. Monitor your end-to-end delivery rates, not just API response rates, to catch these carrier-side issues.
How do I get alerts when Twilio goes down?
Subscribe to email, SMS, or webhook notifications at status.twilio.com, or use Better Stack / API Status Check Alert Pro to monitor Twilio API response rates and error codes. For business-critical SMS flows (OTP, payment confirmations), set up alerts on your own delivery rate metrics in addition to Twilio's status page.
