Hey there! As a very brief introduction, we're an organization in the position of requesting SSL certificates for other organizations. We're running a custom ACME client which we've used to successfully provision a couple dozen certificates so far. I'll venture to say we have a basic understanding of the ACME protocol and Let's Encrypt's published rate limits ([Rate Limits - Let's Encrypt](https://letsencrypt.org/docs/rate-limits/)). However, we've hit a "Certificates per Registered Domain" rate limit in our attempts to obtain a certificate for the [go.linuxfoundation.org](http://go.linuxfoundation.org) domain: > Error creating new cert :: too many certificates already issued for: [linuxfoundation.org](http://linuxfoundation.org) This is confusing because a search on crt.sh ([https://crt.sh/?q=linuxfoundation.org](https://crt.sh/?q=linuxfoundation.org)) reveals that there have been 5 certificates issued by Let's Encrypt for the [linuxfoundation.org](http://linuxfoundation.org) domain in the past week. Including our request, this should be well under the 20/week limit published in the rate limit documentation. Can anyone provide any insight or clarify any misunderstanding on our part here? ---

Hi @pd-aray, > [@pd-aray](#): > > This is confusing because a search on crt.sh ([https://crt.sh/?q=linuxfoundation.org](https://crt.sh/?q=linuxfoundation.org)) There are more than 5 certficates... keep in mind that your search is not covering certificates issued for subdomains. Use this to search for subdomains: [https://crt.sh/?q=%.linuxfoundation.org](https://crt.sh/?q=%25.linuxfoundation.org) Cheers, sahsanu ---

Thanks so much for pointing that out @sahsanu, that’s exactly what I was missing! ---

And if you remove the dot after the `%`, you’ll get everything: the base domain ánd all subdomains… ---
