Apple, Google, Microsoft, and Mozilla ban Kazakhstan's MitM HTTPS certificate

The certificate had been in use since December 6, 2020, when Kazakh officials forced local internet service providers to block Nur-Sultan residents from accessing foreign sites unless they had a specific digital certificate issued by the government installed on their devices.

While users were able to access most foreign-hosted sites, access was blocked to sites like Google, Twitter, YouTube, Facebook, Instagram, and Netflix, unless they had the certificate installed.
