That could change at any time. They could move to an Italy datacenter owned by a different company and that would be just fine.

But whether they're making a promise to stay in the EU specifically? Or whether they might expand to territories that aren't physically in Europe? That could matter, and the FAQ doesn't tell us.

(And yeah the line at the top says 100% EU but that's not the full picture.)

I hope they also have a backup outside Paris.
