FYI our DNS requests to resolve login.microsoftonline.com are failing
because of a DNSSEC error.
There's no DS record for microsoftonline.com so you shouldn't have any
DNSSEC problems with it - my servers can resolve it OK. DNSvis doesn't
show any problems. The only thing which might cause trouble is the
SERVFAIL responses to DNSKEY queries flagged by the Verisign DNSSEC
debugger.

4 recursive DNS servers here still fail to resolve login.microsoftonline.com.
I turned DNSSEC validation off on one and it then resolved correctly.
