Router Configuring, Patching, Port Forwarding and Loads more massive servers on a Monday Morning!

So today I caught the Oxford Tube at 0630, to spend the day working for a company that sets up and maintains networks in some of the trading firms in Mayfair London. There had been a big changeover of hardware over the weekend, which had caused problems,  and the firm contracted to fix this didn't have enough staff to fix something on that scale while casing minimum inconvenience to clients.
Got to say, I learnt quite a lot about how all the network stuff I've read about is actually used in real world and large scale systems. Also really enjoyed seeing all the fancy Mayfair London offices, and not to mention getting a days pay ;)
