[MAINTENANCE] National | Route Server 2 | BGP Daemon Upgrade

Scheduled for Oct 23, 00:00 - 04:00 NZDT

Scheduled

NZIX engineers will be progressively upgrading the BGP software on each exchange’s Route Server 2 to resolve an unsupported capability (RFC 9234) that recently caused a malformed update to propagate to peers. This work is being scheduled with shorter notice due to its severity and the redundancy provided by Route Server 1.

Start: 23/Oct/2025 00:00 (NZDT)
End: 23/Oct/2025 04:00 (NZDT)
Window: 4 hours
Expected downtime: Up to 30 minutes per exchange

Members with peering services should expect their BGP session toward route server 2 (RS2) to go down per exchange. Please ensure you are connected to Route Server 1 (RS1) on your relevant exchange to avoid impact. Session status can be confirmed via https://lg.ix.nz and for convenience each route server address is listed here.
