What is a website render blocking resource?
An explanation of blocking resources on websites.
The easiest way to check is to use curl on the command line. On Mac/linux Open up a terminal, on Windows open the Start menu, type cmd in the search box, and press Enter. Then type in:
curl -svo /dev/null https://www.yourdomain.com
this will retrieve the headers for a request, in the list of returned headers should be one with the name:
peakhour-id
if this is not present then Peakhour is not currently accelerating your website. There are two things to check from here:
DIG your domain name and check that the returned IP address/CNAMe is the one provided by Peakhour in your sign up instructions. If you are using a Mac/Linux based computer open up a terminal and type in:
dig www.yourdomain.com
If you are using windows or are uncomfortable using the command line you can use the google toolbox, choose an A record to dig against as that will work for CNAMEs as well.
If your DIG returns Peakhour IPs and the peakhour header isn't present and your domain isn't in passthrough mode then contact us
