@SimonWMX Just to be clear, (and to anyone else reading), I didn’t actually receive a quote from Netlify regarding using their “High-Performance Edge”, there’s more details on my specific quote here:
It’s possible that using the “High-Performance Edge” may actually be more expensive than I’d mentioned.
You could absolutely host your assets elsewhere and just link them in to the site, this would be no different than having your assets coming from the cdn of any of the cloud based CMS’.
I know you said “Cloudfront” (which isn’t the same thing), but just be aware that Netlify advise that you not put “Cloudflare in front of Netlify”
I’m not sure where the CDN locations are for other providers, but you could perhaps give them a test and see which one provides you the with the best speed/cost benefit ratio.
