I think we can disregard the "ICANN fubared" theory.
microsoft.com NS DNS7.CP.MSFT.NET
microsoft.com NS DNS6.CP.MSFT.NET
microsoft.com NS DNS4.CP.MSFT.NET
microsoft.com NS DNS5.CP.MSFT.NET
This matches whois ("whois microsoft.com" is somewhat entertaining
btw). Furthermore:
DNS4.CP.MSFT.NET A 207.46.138.11
DNS5.CP.MSFT.NET A 207.46.138.12
DNS6.CP.MSFT.NET A 207.46.138.20
DNS7.CP.MSFT.NET A 207.46.138.21
Of course I don't know anything about their network topology, but
it looks like their nameservers are located at one or perhaps two
locations within the msft.net. Traceroute to all of them stops at
the same place, one jump of alter.net, so they all share one point
of failure it looks like.
This does not tell us anything about what failed and how though.
