During this maintenance window we'll be switching from our Avalon (Wellington) site to our Albany (Auckland) site, and we expect no registrar impact.
The front-end change is transparent and should have no impact on registrar systems, however if your application caches DNS records without handling TTLs or your recursive DNS servers are mangling TTL values and enforcing a longer TTL then you may encounter issues.
If you encounter any issues following the change, please contact
registry@internetnz.net.nz.
