Why habrahabr.ru still doesn't have SSL/TLS?

Question

Habr

And by the way, why is SSL / TLS still written through a fraction, SSL could no longer be indicated?

Answer 1

https there, strictly speaking, is. Even with a valid certificate. Just redirect to http.
So they're getting ready - brushing up the code and etc.
In practice, I can say that transferring a self-written project to https is often a pain - in too many places the scheme is hardcoded.

Answer 2

I will be original and answer the second part of the question.
SSL/TLS - because most servers today are configured to support both protocols.
SSL is still very common. TLS is still not supported by all client software and therefore many servers are configured to support SSL along with TLS.
