Depends greatly on the nature of "Armageddon".

They all have redundant power, so assuming Armageddon didn't cause
physical damage to the exchange, and any electrical pulses were minimal,
they'll presumably work till the batteries run down.

Some government telecommunications were hardened to survive nuclear
attack during the cold war. How much of this is anything to do with BT
I'm not sure, the contracts weren't directly with BT when I last read
about it in the Financial Times.

With their comparative lack of wires, and lots of use of microwave
links, might be interesting to compare robustness of mobile phone
networks. I'm guessing bits might survive better against certain common
types of catastrophic event, but I doubt they'd be usefully usable
unless it was designed in given how fragile a lot of the technology is.
