As SANS ISC shares — Moving to modern & more secure server standards are gradually occurring as newer protocols like TLS 1.3 are replacing less secure solutions like SSL that are more open to “hack attacks”.

TLS 1.3 is now supported by about 1 in every 5 HTTPS servers (sans.edu)

TLS 1.3 has been with us for couple of years now. It has brought significant security improvements over previous TLS versions & the number of servers which support it seems to be slowly increasing.   As you may see from the following chart, which is based on data I’ve gathered over the past three months from Shodan.io, TLS 1.3 was supported by over 20 percent of all HTTPS servers on the internet during the last quarter of 2020.   That is because the support for SSL 2.0 has been steadily dropping.  HTTPS servers supporting this outdated protocol fell bellow one million and currently only about 1.5 percent of all HTTPS servers on the internet still support its use.
