Cloudflare has long been doing work on PQ (sometimes in conjunction with Google) and rolled out PQ encryption for our customers. You can read about where this all started for us 7 years back: https://blog.cloudflare.com/towards-post-quantum-cryptograph... and four years ago rolled out PQ encryption for all customers: https://blog.cloudflare.com/post-quantum-for-all/

The big change here is that we're going to roll out PQ authentication as well.

One important decision was to make this "included at no extra cost" with every plan. The last thing the Internet needs is blood-sucking parasites charging extra for this.
