Yes, BGP updates.

Um, it wasn't a trick question Jay, and as others have stated, since
the providers are statically routing this address space to their
common customer, this would require a coordinated effort to manually
(or preferably automatically) shutdown the advertisement should
connectivity be lost to the customer.  There are a number of ways that
could be achieved, but it's obviously important that it is.
