In 2015 I organized a tour of data centres, internet and energy infrastructures to explore the question why data centers are built where they are built (https://test.roelof.info/projects/infrastructours/).
After the tour there was a lunch where people could make their own Double-Irish Dutch Sandwiches.
The recipe helps complete the picture of what makes "a good environment" for a multinational company and their data centers.
I rediscovered it again the other day and added it to my blog: https://test.roelof.info/log/double-irish-dutch-sandwich/
