Outage Start Date & Time:
Outage End Date & Time:
Environment: Production
Participant Impact and Requirements: The following impacts are expected to participant connectivity during this planned outage:
IPWAN Participants - A brief interuption of up to 60 seconds while services are failed over from QLD to NSW Datacenter.
Lan-2-Lan VPN Participants (IPSEC) - Up to 4 hour outage for participants who have established their VPN connection/s via the AEMO QLD datacenter termination point (202.44.76.10 for Policy Based VPN's or 202.44.76.12 for Route Based VPN) only - All L2L connections should be established to both QLD / NSW.
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 NSW datacenter termination point (202.44.78.10 or 202.44.78.12) prior to this scheduled outage. *** Failure to do so will impact connectivity to Marketnet Services ***.
B2B VPN - No impact is expected.
SSL VPN Participants: None expected as DNS entry will be updated to remove QLD IP.
GASHUB: A brief interuption of up to 60 seconds while services are failover from QLD to NSW Datacenter.
Other Impacts will have been communicated in advance.
