> Spread your name servers, and use short-TTL weighted CNAMEs, defaulting to say, 99% Cloudflare, 1% your internal load balancer. The minute Cloudflare seems problematic, make it 0% 100% to bypass Cloudflare’s infrastructure completely. This should be tested periodically to ensure that your backends are able to scale & take the load without shedding due to the lack of CDN.
If your service does scale at first place, then you don't need Cloudflare most of the time.
