Slow page load for an unknown reason

What is the issue you’re encountering

Hi. My site has started being slow yesterday for an unknown reason. Nothing has changed. It doesn’t happen on every page, only seemingly uncached pages. I have been in contact with my host support and tested the site using the hosts file and it is all loading fine. When I remove hosts, certain pages are incredibly slow to load. This hasn’t happened before and nothing changed on site yesterday to trigger this. My host provider has pointed to Cloudflare potentially being the issue.

What steps have you taken to resolve the issue?

Contacted host who ran through a range of troubleshooting. Used hosts file to bypass Cloudflare and the site performs perfectly. I haven’t tried disabling Cloudflare yet. Wanted to post this to support before trying that.

What are the steps to reproduce the issue?

Clicking around the website, some pages will take up to 40 seconds to load. Happens on all browsers and incognito. Tried using a VPN and the same still happens.

Hi there, first of all, we’d like to invite you to check the Cloudflare Observatory that can help you understand why your website is slow:

We recommend you to test the performance of your website using the Speed Test under Speed → Observatory in the Cloudflare Dashboard.

You can then find more details here on how to understand the results.

Regarding your performance issues, we do need more information. Please share the following information with us so we can investigate further:

  • What you are using to measure and test site performance. If you are using an online reporting tool, for example, please provide us with the URL linking to the report

  • A specific URL that is slow

  • The output from running the following command:

curl -svo /dev/null -w "Connect: %{time_connect} \n TTFB: %{time_starttransfer} \n Total time: %{time_total} \n" https://<SLOW URL>

  • The output of the following webpage in a browser: http:///cdn-cgi/trace

  • An MTR or traceroute to <HOSTNAME> from an affected device
