I have page rules set so that everything as cached domainname.com/ and this was working fine. Checking analytics and now we are seeing that there are more uncached requests that cached requests. Any idea why this would start to happen.
That happens to me too. Without more insight to the actual visitor request, I can only guess a few of the following:
My cache at Cloudflare was flushed. Either due to Edge Cache TTL expiration, or some other Cloudflare server at whichever datacenter is now handling requests. I don’t think cached data is shared between servers in each POP.
Your site is being crawled from somewhere new.
In either case, I sit tight and hope it settles down as my site data is cached in more and more datacenters.
