Ok Zippy. If you read the article it had to do with IMPORT TARIFFS WILL RISE. So they are claiming their costs to build data centers in the UK MIGHT increase. Try reading sometime moron.
Woosh! Ok Nimrod, I was trying to explain how Brexiteers think, not necessarily why Microsoft is scrapping it's plans to build that datacenter. If it makes you feel better that probably has more to do with a combination of red tape, legal issues such as data protection and a whole host of intangible issues than it has to do with tariffs. Either way the result is the same, the UK leaving the EU is causing businesses to at least contemplate leaving the UK and that apparently includes Microsoft and it's datacenter. What lies ahead of the UK is two (probably more) years of negotiating how to leave the EU. If the UK is lucky those negotiations will also settle what access the UK has to the EU common market which not looking good at the moment given the declarations of UK politicians who seem to be nursing a boner for hard-Brexit and reverting to WTO rules. Even then the UK still has to re-negotiate the whole portfolio of free trade agreements it currently has had access to through the EU with countries all over the world. That is a process that can easily take a decade to complete assuming the UK has completed common market negotiations by the time it starts tackling this stack of negotiations. All of this translates into risk and if I was Microsoft and I still could move that datacenter into the common market I would do that without delay. Staying in the UK represents risk, moving into the EU common market represents less risk, it's a no-brainer.
