The expense part is arguable, but they may be correct about the lead-time. I'm seeing more than 6 months for provisioning here, for T3s. I hear similar numbers everywhere else. However, microwave towers take almost as long, and are even MORE expensive (the permits alone, might take that long and *then* you have to acquire the rights-of-way and build the towers<sigh>). Depending on frequency of occurance, it might be far cheaper to burn a DAT tape, or DVD-R, and drive it the 20 miles. You might want to consider doing this until the T3 gets installed. It all depends on what the transfer is worth (it looks like a data synchronization run). If is is a data-sync run then they might want to consider a lower-speed line and sync RDBMSs, such as with Oracle Replication Services (Assuming that it *is* RDBMS data and they *are* using Oracle [Sybase works too]). The bottom-line is that, they look like they have a systems architecture problem that they are trying to fix with a claw-hammer. Everything is possible. It is just that certain versions of "possible" cost more than others.
