SMS Delivery Delays and Failures from Twilio to VIVACOM Bulgaria

minor monitoring

We have observed a recovery in SMS delivery from Twilio to VIVACOM network subscribers in Bulgaria and are monitoring service stability. We will provide another update in 2 hours or as soon as more information becomes available.

Components the vendor reports as affected: MMS Long Code, North America Degraded Performance Voice, APAC Degraded Performance MMS, APAC Degraded Performance Voice, Europe Under Maintenance Lookup Line Type Intelligence [Legacy API] Degraded Performance

A component listed here does not necessarily mean a full outage — large providers routinely report maintenance on individual locations. It only affects the verdict above when the vendor marks it major or critical and our own checks also saw Twilio fail from enough regions to rule out probe noise.

Reachability by region

Each region runs its own request from a different part of the world. A service can be up for one continent and down for another, which is usually the first sign of a routing or CDN problem.

What Twilio does

Twilio is a cloud communications platform that provides APIs for SMS, voice calls, video, and email. It enables developers to programmatically send text messages, make phone calls, and build communication workflows. Twilio powers critical communication features for companies like Uber, Airbnb, and thousands of other businesses.

What an outage looks like

When Twilio is down, SMS messages fail to send or are severely delayed. Two-factor authentication codes delivered via Twilio will not arrive, locking users out of accounts. Voice calls placed through Twilio's API will fail to connect, and WhatsApp Business messages may not be delivered.

What to do about it

Check status.twilio.com for the status of specific products (SMS, Voice, Verify, etc.) and regions. If you rely on Twilio for 2FA, have backup authentication methods available like authenticator apps or backup codes. For critical SMS, consider a secondary SMS provider as a failover.

Is it down for everyone, or just you?

If this page says Twilio is up but it is not loading for you, the problem is between you and them. Run a check against any URL from up to 17 cities across three regions to find out where it breaks.

Twilio outage FAQ

Will my 2FA codes arrive if Twilio is down?
No, if the application sending your 2FA codes uses Twilio and Twilio's SMS service is down, you won't receive the code. This is why security experts recommend using authenticator apps (like Google Authenticator or Authy) as your primary 2FA method rather than SMS-based codes.
Are my queued messages sent after Twilio recovers?
Messages submitted to Twilio's API are typically queued and delivered once service is restored, but delivery order and timing are not guaranteed. Messages that failed at the API level (returned an error) will need to be re-sent by your application. Check your Twilio message logs for delivery status.
Does a Twilio outage affect WhatsApp Business messages?
Yes, if you send WhatsApp messages through Twilio's API, those messages will be affected by a Twilio outage. WhatsApp itself may be working fine, but the Twilio-to-WhatsApp bridge won't function. Direct WhatsApp messaging is not impacted by Twilio's status.
How can I build redundancy for critical Twilio workflows?
For mission-critical communications, configure a secondary SMS provider like Vonage, Plivo, or Amazon SNS. Implement automatic failover in your application code that switches providers when Twilio returns errors. For 2FA specifically, offer authenticator app options alongside SMS.

How we measure this

  • We request Twilio's public endpoint every 30 minutes from Fly.io regions across six continents — the most recent check ran from 17 of them.
  • A region counts as down only when it gets no usable HTTP response. A 403 or 429 means the origin answered and refused us, which we report as blocked, never as an outage.
  • A single failing region is treated as probe noise. We only change the verdict when two consecutive cycles agree.
  • Response times average only the regions that actually served the page, so a timeout never inflates the number.
  • Where Twilio publishes an official status feed we read it too. An all-clear from the vendor can soften an unconfirmed degradation; a vendor-declared outage only worsens our verdict when our own checks corroborate it.
