Today I got this while trying to verify www-admin-panel.xyz.europa.eu :
"type": "urn:acme:error:rateLimited", "detail": "Error creating new cert :: too many certificates already issued for: europa.eu: see https://letsencrypt.org/docs/rate-limits/", "status": 429
Is it the case that letsencrypt thinks that europa.eu is a domain? If yes, then maybe it should be considered as a TLD (and not a domain) because there are tons of independent European agencies that have their sites under *.europa.eu. e.g:
All these are separate entities who manage their DNS namespace on their own. I don’t think that the amount of registrations of one should interfere with the other’s.
