It's not that simple though.
It's not like you get the permit before you have even bought the land and designed the plans/architecture/engineering for the data center.
You have to do all of that first, and only once all of that is done, can you submit for a permit.
Which can take not just months, but maybe even a year (or more).
So the situation is, regulation changed during the planning phase. So what do you do now? You obviously can't deliver on a contract that would cause you to break new laws/regulations - that didn't exist when you started all of this.
