@flandish This is no backdoor. This is an denial of service. It’s a big difference. I have to estimate the risk and decide if I want to take it. ZeroSSL uses the infrastructure of Sectigo, an US company. Sectigo can pull the plug very easily. So it is no alternative. Maybe Actalis or Certum are good alternatives. But the government of Poland has not been unproblematic in the past.

@robear My favorites: desec.io and dnyv6.com. Both support IPv4 and IPv6.
