Participant Impact and Requirements: The following impacts are expected to participant connectivity during this planned outage:
IPWAN Participants - Nil
Lan-2-Lan VPN Participants (IPSEC) - Up to 1 Hour outage for participants who have established their VPN connection/s via the AEMO NSW datacenter termination point (202.44.78.10 for Policy Based VPN and 202.44.78.12 for Route Based VPN) only - All L2L connections should be established to both QLD / NSW.
B2B VPN - Up to 1 hour outage to TNSPs with B2B VPN to AEMO NSW Datacentre if VPN connection is only terminating in NSW only.
SSL VPN Participants: None expected as DNS entry will be updated to remove NSW IP.
GASHUB: Nil
Note: Participants are encouraged to ensure their VPN connections are already established or are configured (as per AEMO best practice) to automatically failover to the alternate AEMO QLD datacenter termination point 202.44.76.10 for Policy Based VPN and 202.44.76.12 for Route Based VPN) prior to this scheduled outage.
