Be careful where you query. There's not necessarily any relationship to
the times when the NSI WHOIS database is updated and the times when the
gTLD servers are updated.
The new NS records are in the right place now:
$ host -r -Z -t ns microsoft.com a.root-servers.net
microsoft.com. 172800 IN NS DNS4.CP.MSFT.NET.
microsoft.com. 172800 IN NS DNS5.CP.MSFT.NET.
microsoft.com. 172800 IN NS DNS7.CP.MSFT.NET.
microsoft.com. 172800 IN NS DNS6.CP.MSFT.NET.
microsoft.com. 172800 IN NS Z1.MSFT.AKADNS.COM.
microsoft.com. 172800 IN NS Z2.MSFT.AKADNS.COM.
microsoft.com. 172800 IN NS Z6.MSFT.AKADNS.COM.
microsoft.com. 172800 IN NS Z7.MSFT.AKADNS.COM.
In any case it is possible to list additional NS records in your zone in
order to achive higher reliability for your DNS in the case where the
registered servers are only intermittently available.... Note that this
doesn't help for long if the registered servers are totally unreachable
for longer than the TTL on the additional un-registered NS records.
