Enabling HA and SDN on Existing Typesense Cloud Cluster

TLDR Ross asked about enabling HA and SDN on an existing Typesense Cloud cluster. Jason confirmed a resulting downtime and the need for a setup like Cloudflare DNS for maintaining same hostnames.

Does enabling HA on an existing Typesense Cloud cluster involve any downtime? Or just spins up an additional 2 clusters (e.g. 1->3)

As a follow-up, same question but going from non-HA + non-SDN cluster, to HA+SDN (3 regions).

Is there any way to make the hostname for the SDN cluster the same as the existing (non-HA, non-SDN) cluster?

There is indeed downtime as we upgrade an existing cluster to enable HA.

We are unable to turn on SDN on an existing cluster, so I guess the questions don't apply.

Not on the Typesense Cloud side, but if you setup something like Cloudflare DNS (with proxy turned on), then you can keep the hostnames the same across clusters.
