What about a small laptop (Asus etc. with Flash drive), a 3G modem and
a couple of USB-serial adaptors?

Use DynDNS, then you can log into the laptop over SSH and then into
your front-line routers and switches over the USB-serial links.

Once you get your front-line stuff back, you can start logging in
remotely to fix other stuff up.

Also, put the laptop onto your internal network so that you can
directly connect to other internal systems (including some with serial
connections to other internal switches and routers etc.)

All assuming you get good 3G signal in your data centre and that your
3G plan is cheaper than an ADSL plan with phone line rental etc.
