[dns-operations] What's going on at Microsoft?

Hi,

Right now I have quite a lot of pollution on my recursive error logs due to two Microsoft operated domains:

microsoftdnstest.net
msedge.net

The errors begun on October 17th. And I get the same SERVFAILs querying public recursive DNS
services such as Google, Quad9, etc.

Is there anyone from Microsoft here? I see both domains are broken according to dnsviz.net. 

Thanks,




Borja Marcos.

P.S: The offending queries are:


www.microsoftdnstest.net
ns1.microsoftdnstest.net
ns2.microsoftdnstest.net

t-ring-fallback.msedge.net
t-s2-ring.msedge.net
t-ring-fallbacks2.msedge.net
t-ring-fallbacks1.msedge.net
