End of Support for TLS 1.1 and older in Twilio Console and services.twilio.com

Starting March 11, 2024 Twilio Console and services.twilio.com will no longer support TLS version 1.1 and older, and outdated cipher suites. This is part of an important security upgrade to our systems.

The following cipher suites that will no longer be supported in Twilio Console:

• ECDHE-ECDSA-AES256-SHA
• ECDHE-RSA-AES128-SHA
• ECDHE-RSA-AES256-SHA
• AES256-SHA
• AES128-SHA

Cipher suites in services.twilio.com will not be changed
