Rate Limit for different domains requested from same IP



I will be providing hosting per day approximately for 1000 different domains from my big apache server.

I will be requesting 1000 certificates for the day from the same IP address for different domains, is it possible?

will the renewals will be possible after 90 days?

Thanks for your help.


You can find information about the rate limits on the Let’s Encrypt website: https://letsencrypt.org/docs/rate-limits/


Thanks for the reply, I have seen this, but from one IP there is a restriction that " 10 Accounts per IP Address per 3 hours.".
How to getride of this limit for my situlation, is there any way?


It depends on you…
Normally, you would be able to use the same account for all domains on this server. (Or you could do domain per account, depends on your hosting software)

Beside a “Apache server”, are you using any control panels for this? (Like cPanel, Plesk?)

Thank you


No, I am not using any CPanel or Plesk. only Apache server


In our integration guide we recommend hosting providers use one shared ACME account for issuing certificates instead of one account per certificate/client.


“In ACME, it’s possible to create one account and use it for all authorizations and issuances,”

what does it mean?
Can I use same certificate for all the domains?


The “account” is a “user” account - who you are.
NOT a certificate - what you will secure.


what is solution here for 1000 domains per day?
I mean with single account , how can I get/authorize all 1000 domains.?


Most ACME clients register an account the first time you run them, and then reuse it afterwards. If you use a typical client, and follow its documentation, it won’t be a problem.

Issuing 1000 certificates may take you 10 hours, though.

For users of the ACME v2 API you can create a maximum of 300 New Orders per account per 3 hours.
