NextDNS resolves at.alicdn.com to Russia instead of EU?

Hi,

recently I have had some trouble accessing a cloud portal for my solar inverter - I find out that they use at.alicdn.com to host some elements - for me it resolves to at.alicdn.com.danuoyi.alicdn.com (47.246.2.253) which is in Russia (and russian IP adresses are blocked).

The hostname resolves to (faster) european IP addresses using other DNS servers, like Google etc.

https://ping.nextdns.io/ shows that I am i fact using a local DNS in Denmark:

  zepto-cph    10 ms  (ultralow2)

■ anexia-cph   10 ms  (anycast2, ultralow1)

  anexia-osl   17 ms

  zepto-sto    18 ms  (anycast1)

  zepto-ber    18 ms

  anexia-sto   18 ms

  zepto-ams    18 ms

  zepto-osl    21 ms

  anexia-ams   30 ms

  vultr-ams   118 ms

I am not using any VPN etc and my IP is also in Denmark. I have made a "fix" creating a static entry for the hostname/domain but that might break...

Does anyone know why I am directed to a Russian IP instead of a local one?

      NextDNS anonymized ECS is exposing an IP in the right country. The DNS auth of at.alicdn.com using probably an outdated Geo IP database.
