You can no longer order "direct" lines to SIAC unless you have an
extremely compelling reason. Nowadays you must order a line to "SFTI"
which is their Disaster-Recovery-centric service. You are correct about
the connection method, but he will need to be specific and understand
that he wants to connect to SFTI and not just "SIAC" directly anymore.
