The folks on this list likely know where the central Tennessee backup tandem office is located. Although its semi-public knowledge, I avoided mentioning its location until the immediate threat passed. LATAs don't have much legal meaning anymore, but every LATA had at least two tandem offices.
Nevertheless, the "cloud" still depends on physical infrastructure.
I'm sure there will be several investigations by regulators why all the 911 PSAPs didn't fail-over to the backup tandem office. Of course, single-homed circuits physically connected to the Nashville CO wouldn't fail-over.
Amazing how much data is in LERG. -Nathan
