Change End Date & Time: 15/06/2026 17:00:00
Outage Start Date & Time:
Outage End Date & Time:
Environment: Pre-Production

Participant Impact and Requirements: AEMO's FRC Gas Hub web services need to have their server certificates updated every 3 years with new certificates to replace expiring ones.

Participants connecting to these endpoints or receiving requests from AEMO's FRC Gas Hub platforms and have authorisation mechanisms like certificate fingerprinting in place will notice a change in AEMO's server's certificate fingerprint and will need to update their systems accordingly.

The certificate relates to the FRC HUB RELAY, participants WILL need to update the profile that communicates with the FRC HUB RELAY with the new root(AEMO-RCA G2)/intermediate(AEMO-ICA-TEST G1) and FRC-HUB-RELAY-Prod certificates.

This will need to be done to avoid the inability to send messages to the relay.

The certificates can be downloaded from the link below:
