I'm seeing about 50% packet loss to all 4 microsoft.com nameservers.  I
can't get any dns responses from them.
The following is all hypothesis:

Reading the MS announcement that says "At 6:30 last night, a configuration change was made by a Microsoft technician to the routers on the edge of Microsoft's DNS network", and adding in the 50% packet loss you list above, it looks like the MS technician installed some sort of Cisco TCP/UDP rate-limit on some interface along the data path.
