Traefik dns challenge
Hi, i have a setup with multiple remote servers, and I want for each of them to host my regional domain: app.example.com (each server different region)
My questions are:
1. If one server has already completed a DNS challenge, do the other servers also have access to that certificate, or do they each need to perform their own DNS challenge to obtain a certificate?
2. If all servers have access to the certificates, is there a risk of a race condition where multiple servers attempt the DNS challenge at the same time? Or do they somehow know that one server is already in the process of validation?
