There goes the EU data Safe Harbor business
This seriously sucks for foreign companies using hosting services in the UK to meet EU data residency requirements. The UK was a great place to park the apps, and came with english language support at no extra charge. Now with the UK out of the EU, it will become much more difficult to explain to continental customers that their data is safe. Before that is the even harder part - explaining this to the sales team - and you can never be sure they don't mess up the message.
So... no choice but to move. Ireland? Germany? Sigh.
