I understand that "the hidden service directory" is "DB" in this diagram:
Do you know how to get this list "manually" ? Is it exposed somewhere
publicly ? Can I download it as file ?

I still don't understand one step here
why client cannot communicate with hidden service using "Introduction
points" but they try to establish connection using other machines
If they switched some information thought one channel, why cannot they
communicate all the time ?
