Rate limit and accounts creation for 100K domains on caddy

Help

  1. We manage it with 20 servers (with the option to scale when needed) that share the same Caddy config.
  2. Yes, we use one LE account because this is how CaddyServer is working and Let's Encrypt recommendation.
  3. We use other CAs, such as ZeroSSL and Google (new option), but they all have rate limits or respond very slowly after too many requests.

Our system has been working amazingly well for years. However, we are currently facing an issue with the rate limit imposed by Let's Encrypt. I am exploring the possibility of resolving this by changing to CaddyServer, or alternatively, it would be great if Let's Encrypt could provide an option to pay for extra rate, as I have suggested previously.
