Re: Insane
What he said. Lord knows I don't agree with El Sergio very often, but I certainly do here.
And while we're piling on objections, I forgot to note that the UK has some of the highest electricity prices in the G20 so the economics for siting a datacenter in the UK, let alone London, are questionable. I am very familiar with the latency argument for HFT, but there are only so many banks - and the Docklands is already well supplied with Datacenters.
In short: very high electricity costs, astromically high land costs, high environmental impact (heat in a heat island), negligible job creation and whatever profit remains is offshored. Whatever reasoning process is driving this, it isn't obvious.
