At many non profit IXes the interface size to the fabric is public data and published by both the IX and on peeringdb. Such as at the SIX. They have not yet upgraded to 1x100GbE.
Another regional example, they have 20Gbps to the VANIX.
What is opaque is the size and scale of their PNI peering, which parties generally don't share. For example in a mid sized city where Comcast is the cable monopoly they almost certainly use a 100GbE interface direct to Comcast for just that isp.
Yes the scale is terabits globally. But it is highly decentralized.
Yes, it's exactly the point. What I was saying is I am not off by an order of magnitude, I know exactly how big they are. Two ASes I do engineering work for peer directly with cloudflare.

Your post implied a total of 200-400gb, the real number is 10x that (otherwise known as “order of magnitude”). I’m not disputing your knowledge or experience, but the post as written has issues.
no, my post was quite specifically about a single IX point in one geographical location, and was accurate. You confused me talking about interface sizes and counts at one IX point with cloudflare as a whole.
What difference does it how much they have as peering in one specific geo? Are you going to posit then that that is their capacity in that geo? I hope not, as Cloudflare has their own backbone and could easily and efficiently exchange traffic outside the geo depending on peering agreements.
