Cannot reach anycast 2a07:a8c0:: from South Africa

Hi, 

I am experiencing connectivity issue to NextDNS primary anycast 2a07:a8c0:: address on IPV6 from South Africa.  Anyone else with the problem?

    Same issue here, though I'm in the US and experiencing it. Both 2a07:a8c0:: and 2a07:a8c1:: are unreachable.

    @NextDNS -- any help here, please?

       Thanks for the reply! Yes, I'm able to reach other IPv6 just fine. For example:
