Communication
Twilio
Twilio is a cloud communications platform with APIs for SMS, voice, email, and WhatsApp used by developers to embed messaging directly into their applications.
What is Twilio?
Is Twilio down? Twilio is a cloud communications platform founded in 2008 by Jeff Lawson, Evan Cooke, and John Wolthuis, providing APIs for SMS, voice calls, WhatsApp, email (through SendGrid acquisition), and other communication channels that developers embed into applications. Twilio's developer-first design philosophy — offering a phone number, an API key, and a few lines of code to send an SMS — made it the infrastructure layer for communication features in hundreds of thousands of applications across every industry. Twilio went public on the NYSE in 2016 and grew to process billions of messages and calls monthly.
Twilio powers critical communication infrastructure for applications ranging from Uber's driver-rider messaging to two-factor authentication SMS systems at banks, appointment reminders at healthcare providers, and marketing campaign delivery for retailers. The breadth of its use cases — anywhere an application needs to communicate with users via phone or text — makes Twilio a foundational component of the modern web stack. Twilio acquired SendGrid (email) and Segment (customer data platform) to expand its communications data capabilities.
Twilio outages propagate immediately into every application that uses Twilio for customer communication. When Twilio SMS goes down, millions of users stop receiving two-factor authentication codes, order notifications, appointment reminders, and verification messages — simultaneously across all applications that depend on the platform. Common symptoms include SMS delivery failures, voice call connections failing, 429 rate limit errors from the API, or authentication flow failures caused by non-delivery of verification codes.
