Hello all!
I’m new on the Tor network, since end of 2022 I’ve a running relay on Tor and know I read some explaination / documentation about how Tor works.
First thing, about the Onion Service, I read this article => Tor Project | How do Onion Services work? and I’ve 2 questions:
- When the Onion Service choose the relay to are the introduction point, does the Onion Service choose relay with a specific flag or it’s a little bit random?
- When the introduction point are choosen, with the relay between them and the Onion Serivce, if I understood right it’s the long-term circuit, so does this long-terme circuit is still the same? Ex. if there is the introduction point A1, relay A2, A3 then the Onion Service. So when the Tor browser send the rendezvous point to the introduction point A1, it will always use the relay A2 and A3?
I’ve another question but firstly this one to start 
Note: English is not my main language (french) but feel free to answer in english and use the correct term, I’ve some basic knowledge about network etc…
Thanks in advance 
Cheers
