Anyone not in the US feels this even more since so much online is US hosted, 300ms for every little interaction adds up quick.
Don’t know about that, pretty much everything is hosted on Cloudflare, Azure or S3 these days and all of them have at least one CDN on each continent.
There are CDNs everywhere, true. It is not true that everyone deploys to them all, though. Also it dodges that the networks available to everyone are still not equal.
