I lead the platform team of a fairly young startup in the D2C commerce space in the APAC region. This outage happened during peak traffic hours which made me and the team look like amateurs in the company.

Cloudflare is great, and I would never move away from it. But from a business continuity standpoint, is there a fallback approach that we should be prepared for during such cases?

One crude approach we were discussing is during an outage we could change the NS records in the registrar to point to for eg. Google Cloud DNS which would already be in sync in terms of the DNS records it has.
