Please document how upstream and fallback work

Open timkgh opened this issue 4 years ago • 2 comments

  1. How are upstream servers used? Random, round-robin, fastest ... (--all-servers is clear)

  2. What does upstream not available mean? dnsproxy cannot connect to the server, or it can but gets back a DNS error?

  3. When the upstreams are not available, how are the fallback servers used? In order, random, ...

  4. Does dnsproxy monitor the upstream servers and switches back to them from fallkback, when available again?

Wondering exactly the same things, but can't find any improved documentation now 9 months later. Have done a lot trial-and-error trying to figure out how things work and reading the code, but would be so much better with "black on white" documentation.
