My site never failed thats the thing without paying $20. And many developers can actually do it too. If you can’t serve decent traffic for a static site, I would rather fix the leaking tap once and for all than wasting money on a water tanker every time I am out of water.
What does the $20 buy vs free plan? During a spike I was able to handle 30k pageviews per hour with Cloudflare free plan + $40 vps. Pretty much all pageviews were cached by Cloudflare and didn't hit my server. How does the $20 plan help?
