Scheduled

Please be informed that on September 8, 2025, Contentstack Launch will implement a planned security upgrade to deprecate legacy TLS 1.2 cipher suites.

Start: September 8, 2025, 00:00 UTC
End: September 8, 2025, 03:00 UTC
Duration: 3 hours
Downtime: None

Impact: After this change, only compatible TLS 1.2+ and TLS 1.3 cipher suites will be supported. This ensures stronger encryption while maintaining compatibility with all mainstream browsers, operating systems, and client libraries currently supported by their vendors. Legacy environments that rely on outdated cryptographic protocols may no longer be able to connect.

For further details, please refer to our documentation: https://www.contentstack.com/docs/developers/launch/traffic-encryption#supported-cipher-suites

If you have any concerns about compatibility, please reach out to our Customer Success Team.
