we are using Cloudflare from years ago with Business plan in our domain hsfiles.com.
Today Cloudflare is not serving cached contents as usual and all traffic is being requested to our backend. We have checked and not changed have done in our Cloudflare configuration.
You can see last 6 hours traffic vs last week traffic:
It would appear as if you configured your domain to bypass the cache. Can you post a screenshot of your page rules?
Check whether you have any page rules either bypassing the cache or enabling origin cache-control, while sending a cache-control header from your server which would disable caching.
In that case something on your server side must have changed and now sends caching headers which make Cloudflare bypass the cache. If you check the Cloudflare headers you will notice the status explicitly mentions that the cache is bypassed.
DNS is working. I wouldnt have responded the way I did otherwise
The OP’s site returns cf-cache-status: BYPASS, which is either a page rule or - as we seem to have ruled that out - a cache-control header (or similar) preventing caching on the origin’s side.
