this is not used anywhere since we want to wait for rate limits to be
fixed.
The current limits are :
Rate limit on registrations per IP is currently 10 per 3 hours
Rate limit on certificates per Domain is currently 5 per 7 days
The domains are counted based on https://publicsuffix.org/list/ (not TLD). Like appspot.com, herokuapp.com while not a TLD, it a public suffix. This list allows browser authors to limit how cookies can be manipulated by the subdomain of those domains. like app1.appspot.com cannot go and change things of app2.appspot.com.
This means
a) we cannot use LE for cloudron.me, cloudron.us (or we have to get on that list)
b) even for custom domains we get only 5 certs every 7 days. And one of them is taken for my.xx domain.
