Is Speed Kit compatible with other CDN services?
Since our caching is only employed client-side, other CDN-services should not pose any problems.
The exception can be our backend getting blocked by them because of too many requests. If your site has a huge number of files and a DDoS-protection or firewall in the other CDN has tight restrictions, that might happen. In this case, all you have to do is simply put our servers on the whitelist. The IP-range needed for whitelisting can be found here.
