> If these data centres are rebuilt, you'd maybe expect them to be rebuilt in new locations behind existing _permanent_ (and seemingly quite expensive) air/missile defence batteries in Bahrain

I've seen data centers that were built to withstand an aircraft impact (they were located on a major airport flight path). I wonder if they'd rebuild these to that standard or something even stronger, given these attacks. It probably wouldn't help much against ballistic missiles, but it might make it more resilient against drone attacks.

Here's a Google Maps link to BAH53 (Manama), it doesn't look like the hardened data centers I seen (e.g. sloped walls like a bunker): https://maps.app.goo.gl/6DjhQs753p6EHQUu6
