AS4826 leaking at Any2 LA?

We're seeing ~2000+ routes leaking at Any2 LA, originating from AS4826. Our traceroutes to Microsoft were going to LA->New Zealand and back O_o. We filtered them out, but thought other folks should know just in case. I also did call their NOC & send them a copy of my notes - just thought I'd throw this out there! Regards, Randal
