I think this is the best CDN service -

I made a typo mistake when try to link… I made a typo mistake when try to link my domain to quick through LSCWP, then when I realised it later and registered a new Quick accout with my new email, I got advised that my domain was linked to other user account. Quick team helped me to transfer it to my new emaill accout quickly and swiftly. Enjoy it!

Seems promising but... The service seems promising, but it can only be used for smaller sites. The QUIC service needs more intelligent cache flushing as it is unnecessary auto-flushing too much and too often. This creates a lot of pages that are not cached anymore, and they become very slow when loading. As a workaround for the unnecessary cache flushing the crawler can be set to run like each 2-3 hours (instead for 2-3 days) but it creates CPU overload which is not good eighter.

SSL Generate is very long I have 2 sites using Quic CDN, the 2 domains are pointed to Quic already, so I can not use local certificates from my VPS (also lego ssl renew won't work also because domains are pointed to different IP). That's why the best options is using the certificates which are generated by Quic, but their process took very long. Whenever I select "System-Generated" from their admin panel, my sites will be down because Quic did not provide any certificates yet. I dont want my sites are down, so I have to try "Manual Entry", but after 3 months I have to do this process again. Very frustrating! The downtime when setup CDN is not acceptable. I dont know why I took very long to generate free certificates using Let's encrypt. It only took me less than 5min to generate a certifcate for my VPS. (I did try waiting their system provide SSL but few hours later, nothing happen).
