Twilio is launching Edge Locations that improve the performance and security of its Programmable Voice, SMS, Notify, and Webhook Callback APIs by deploying regional connectivity layers closer to users' geographical locations. This enhances the quality and user experience of time-sensitive applications, while also providing additional security features such as network peering or virtual private networks. The new Edge Locations offer improved latency, flexibility, options for network failover, and increased security, making them suitable for mission-critical operations.
