This has happened because of a power generation constraint.

Are there other places where power generation is going to be a constraint in the future? Any chance us-east-1 won’t have enough juice for all the data centers?

The island of Ireland has its own grid, with limited interconnection to the UK grid. us-east-1 is within a much larger grid (the eastern interconnection) which also has more robust interconnection with other major grids. There's a lot more flexibility in connecting new large customers in a larger grid, because there's a tendancy to build towards a percentage over capacity, and a 1MW load is a smaller percent of a larger grid.

That said, a 1MW load is still a lot, so the local transmission utility may not always be able to accomodate it in any particular location, but it should be possible to find somewhere nearby-ish where there's capacity.

There was an article[0] recently about just that thing. In this case the issue is overhead line capacity in the area by us-east-1 rather than generator capacity.

AFAIK the biggest constraints for virtually all DCs is available power and available fibre connectivity (or in the case of places like Singapore, available land).

Singapore's moratorium was ostensibly due to environmental concerns

Presumably there would've been fewer environmental concerns if Singapore simply had more land.
