Routing to Mexico from UK on IPv6

I see from the forums that there have been some routing changes but IPv6 with my ISP (Andrews & Arnold) in the UK is still not very happy. 

My diagnostic report is here:

https://nextdns.io/diag/3ea4f110-a11b-11ee-af01-9991396cd19a

Key section is this:

 

Secondary IPv6: anexia-mex (146 ms)

`ping.nextdns.io` shows IPv6 `anexia-lon` erroring out, and `anexia-mex` comes up for `anycast2` - which is a bit far I guess!

    @nextdns_network  if you are looking at routing atm, I’m still seeing this in the UK. May be related to the other post that’s also routing via Mexico from US?

       Sorry - still the same I'm afraid.

      I feel really bad just sending you errors like this - is there anything else I can do to help you? Do you need my ISP to try anything?

       We'll check it with our upstream provider today and get back to you.

       Great - thank you. I've just done a check again this morning. `anexia-mex (IPv6) 137 ms (anycast2)` still really wants to help serve my dns lookups.
