anycast2 IPv6 is anexia-mow instead of anexia-lon!

Hello,

Once again, the IPv6 routing has screwed up from AANET. I don't understand why this keeps happening - it works for a variable amount of time, then breaks again.

IPv6 anycast 2 is now anexia-mow instead of anexia-lon, which also doesn't make sense - why has it jumped to a server so far away?

I can't provide a useful diag either because your IPv6 test is still failing - ipv6.test-ipv6.is unavailable so the diag assumes IPv6 is unavailable and this is the result: https://nextdns.io/diag/6f195480-acaf-11ef-9bf1-27e76a13fe5a

I did mention this the last time I reported an issue - you need to find a better way of detecting IPv6 than using a domain you don't control which may or may not vanish at some point.

MTR attached, that should be enough to show the issue.

Thanks,

-Will

    Please try the diag again. IPv6 should be fixed.

      Nope, the diag is still not detecting IPv6 on two separate networks that have confirmed working IPv6.

      Although the issue with the secondary is now resolved so this is a moot point:

      But the diag needs to correctly detect IPv6, which it doesn't.

       should be fixed now, for good this time.

      It certainly is - thanks.
