Final Reminder | CHG0102957 | PROD| Enable TLS 1.3 for Gas B2B Hub and disable TLS version 1.0/1.1


The Gas B2B hub servers will be updated to support TLS (Transport Layer Security) 1.3 version. Also the legacy versions 1.0 and 1.1 will be disabled and not be supported going forward. Participants are required to use TLS 1.2 as a minimum protocol to communicate with AEMO, failing to do so will impact the connectivity.

An outage is not expected but, there may be some minor interruptions during the change period. Participants are required to make sure the connectivity is intact post change implementation. In case of any issues noticed, please reach out to AEMO Support Hub.
