Well… i have not the necessary knowledge to make that query of if it is even possible with the collected data.

I believe that over this week Akamai activates the option to widely activate TLS 1.3 if you’re routing through them (https://community.akamai.com/customers/s/article/WebPerformanceGeneralAvailabilityofTLS1320190808175612?language=en_US), and it has been active for a while over Cloudfare.

So, anyone knowns if this can be know? :slight_smile:

Thanks!

I am sure the Archive has ways of providing data on TLS 1.3, but I don’t know the query. In the meantime you might try Qualys’ Pulse. Check out the Protocol Support section… https://www.ssllabs.com/ssl-pulse/

I don’t know of a raw source for this, but here’s something that might lead to that: https://casecurity.org/2018/12/06/ca-security-council-casc-2019-predictions-the-good-the-bad-and-the-ugly/
