    Hi. It would be nice if you make this list complete by including PageCDN. PageCDN has a unique feature set that optimizes website performance to extremes. Content Delivery from multiple POP locations is just the first of several optimizations that PageCDN can do for your websites seamlessly.

    It serves content using brotli-11 compression (that can save upto 30% more compared to gzip), better parallelizes content, provides Fonts CDN (named as Easy Fonts) to save on DNS lookups and solves the ‘Leverage Browser Caching’ issue that you face when using Google Fonts, supports HTTP/2 Server Push and allows private files to be uploaded to the CDN. PageCDN’s WordPress plugin automatically takes all these optimizations into consideration and can provide the best performance that you can expect from a CDN.

    I tried setting up my WordPress press hosting on Google cloud and found it slightly more difficult than expected. I have subbed to your posts RSS feeds so I read it from time to time. This post caught my eye. I have tried Amazon EC2 hosting and a few others I have found that the time you put into setting up the server with proper security takes too long.

    I would rather just hire someone else to do it, or pay for a paid hosting plan. I came across Kinsta WordPress managed hosting. Can you give me your opinion on this company?
