AT&T used to try to avoid centralization, but ended up with routing controlled from Bedminster, NJ.[1] An interesting comment from AT&T's NOC tour guide is that load doesn't vary much any more. AT&T used to have holiday calling surges and such, but now, in an always-on world, overall load is relatively steady.
