Weird routing issues at CDG

No, not aviation routing; IP routing.

From the Terminal 2 American Airlines club, I am unable to hit most * IP addresses. This is significant because it's basically all of Microsoft Azure, including, Weather Now, and a bunch of other sites I use or have some responsibility for.

I've just spent a few minutes testing DNS (everything is fine there) and then using tracert and pathping, and it looks like the entire and ranges are just not visible from here. (The Daily Parker is also in Azure, but its IP is in the subnet, which seems to be visible just fine.)

I wonder if Microsoft knows that its U.S. East data center is being blocked by some French ISP? Or why?
