Are any of your customers multinationals?

Last two companies I have worked with, through a combination of organic
growth, aquistion and partnership have a rather complex mix of PA,
Legacy, RIR assignments in 4 regions, LIR assignments, and so forth. it
would be fairly normal in the course of service delivery to customers to
advertise prefixes obtained in one region in one or more other regions.
One of these entities has a global IP backbone, the other glues it
altogether with vpns, appart from scale they're not really that different.
