Not one single company in the financial sector in the UK wants their kit anywhere near the US or in any datacentres with US ownership any more simply because of the PATRIOT act and PRISM etc.
We just moved 2 tonnes of kit into a wholly UK owned DC away from two large primarily US based DC's. We've also cancelled our Amazon S3 storage option and migrated over 540Gb of data back to our kit.
People have paid for all this voluntarily because being responsble for being fucked over by the US government is a big concern. Would you want all your mortgage, insurance and credit scoring data in the hands of a foreign government who religiously ignore data protection laws?
