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.

Cedexis now part of Citrix offers a multi-cdn product, that allows you to load balance between CDNs, check them out. I'm not sure who else is in that space, but in general it sounds like you want a multi-cdn strategy.

If you're okay with load balancing DNS queries across multiple providers you could do 2x Cloudflare primary NS, 2x GCP for example where each provider is in sync with each other. If not, a manual swap at the registrar level would be good enough. I should also mention this approach sort of breaks with Cloudflare's proxied records which dynamically assign anycast IPs for records placed on their CDN. So if using this approach the failover NS provider would probably need to also use a different CDN, preferably one that just gives you a CNAME.
