I work for a company that effectively hosts websites for our customers, on their own domains. We’d like to use Let’s Encrypt (once it’s fully launched) to automatically issue certificates for all our customers. I’m wondering if there are any sort of rate limiting or throttling issues we’d need to be aware of before embarking on a project like that. We’re looking in the ballpark of 10000-20000 per year, which when business days and working hours are taken into account, probably works out to something on the ballpark of 8 per hour.
Also, is there any sort of “vetting” or scrubbing you do on domain names? If a domain is refused by Let’s Encrypt for some reason, is there a process in place for appealing that?
