Service/ Component: Internet Access
Change Title: QLD Internet Router Refresh
Change Start Date & Time: 25/05/2024 09:00:08 AEST

Outage End Date & Time: 25/05/2024 13:00:21 AEST
Environment: Production
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 2 hour outage for participants who have established their VPN connection/s via the AEMO QLD datacenter termination point (202.44.76.10) 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) prior to this scheduled outage.
B2B VPN - Up to 2 hour outage to TNSPs with B2B VPN to AEMO QLD Datacentre if VPN connection is only terminating in QLD only
SSL VPN Participants: None expected as DNS entry will be updated to remove QLD IP.
GASHUB: No impact is expected as GASHUB is currently operating out of NOR Datacenter.
Other Impacts will have been communicated in advance.
Support Information:
Report any impacts to the AEMO Information and Support Hub or call 1300 236 600.
