A large number of static websites of Invantive are undergoing a change as they are moved to another hosting party within the European Union (see Invantive versterkt continuïteit: Overstap naar Europese leveranciers voor betere zekerheid en onafhankelijkheid). In doing so, the certificates will change.
The certificates previously stated as issuer:
cn = Amazon RSA 2048 M02
o = Amazon
This will be replaced by:
cn = R11
o = Let’s Encrypt
Support for IPv6 (AAAA DNS records) will be removed for now. All websites will remain reachable for IPv4. Your applications will automatically fall back to this.
