AS3549 Level3/GBLX carrying routing for 10.0.0.0/8

This should now be fixed.

As a general matter of policy, we do filter out 10/8, but somehow the filter list for a customer was empty which then defaults to an implicit accept.  We're in the process of improving our config audits to catch this in the future.

I wonder why people don't drop any update that contains stuff like RFC 
1918 space.
