AWS's 3 data centres in me-south-1 are:

BAH53 (Manama): https://www.openstreetmap.org/way/1492345589

  An adjoining substation to BAH53 had one of it's two main buildings damaged/destroyed about 2026-07-16 per https://soaratlas.com/maps/asia-damage-to-data-center-power-substation-bahrain-jul-16th-2026-142024

  Then about 2026-07-22 BAH53 itself was damaged/destroyed per https://soaratlas.com/maps/asia-damage-to-amazon-web-services-bahrain-jul-22nd-2026-142112

  Possibly the least defended of the three sites as there is no air/missile defence battery in between this site and Iran.

BAH54 (Zallaq): https://www.openstreetmap.org/way/1359931661

  No media reports about this data centre being attacked previously. Possibly the safest of the three as there are at least two (probably three) air/missile defence batteries in between this site and Iran.

BAH55 (Hamala): https://www.openstreetmap.org/way/956069872

  Apparently the Batelco DC.1 data centre adjoining (and apparently critical to) BAH55 was damaged/destroyed about 2026-04-01 per https://www.bbc.com/news/articles/cgk28nj0lrjo _or_ the adjoining substation to these two facilities was damaged/destroyed -- news articles are hard to follow as to what exactly might have been damaged and the extent of damage caused.

  Middle ground for defence with one or two (maybe three) air/missile defence batteries between this site and Iran, depending on where drones/missiles are launched from.

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 (https://www.openstreetmap.org/way/1492281507 and https://www.openstreetmap.org/way/1492953902). Based on the permanency of those air/missile defence batteries it doesn't look like the government of Bahrain are expecting things to get safer for data centre hosting in Bahrain any time soon.

Update: IRGC published satellite imagery a few hours ago showing an impact to BAH54, apparently impacted on 2026-07-24, alongside another undated image before the impact. From a quick comparison of both images with reliable satellite imagery sources (e.g. WV02 image dated 2025-02-21 on ESRI World Imagery Wayback) there are no obvious signs of image manipulation, with roof features and surrounding buildings/other features lining up as expected. Additionally the claimed post-strike image adds a significant number of vehicles to the site (when there are usually close to none present), which may correspond to fire fighting vehicles expected to be monitoring the site afterwards. Further, Sentinel-2 imagery from 2026-07-24 shows a dark patch (blast damage) on the roof of BAH54 per https://browser.dataspace.copernicus.eu/?zoom=18&lat=26.0509...

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

    Can you give an example? I find this hard to believe. Why not pick a location not within a "major airport flight path"? It seems much cheaper.

      London has lots of datacentres in Slough (near Heathrow) and Docklands (London City Airport, but also many LHR planes transit over).

      AWS/Azure/GCP/etc Colo in Equinix/Telehouse datacentres there, and those Docklands locations in particular were picked based on location to LINX (major London peering/interchange), and LINX was put in Docklands out of desire for relatively proximity to telcos, and London’s banking/finance industry.

      At least one colo facility I’ve been was an ex-defense facility. And it had reasons to be where it was, and to be hardened.

    I think the two kinds of attacks are so different that they require different defenses.

    Drones need not fly in straight lines. Data centers need ventilation, providing a path for drones. Putting grids in a ventilation shaft will stop the first drone, but a coordinated attack will use one drone to blow up defenses and a second/third/etc one to reach the target

    It is probably far cheaper to simply have global redundancy for the data and compute than to put the datacenter in a bunker.

    Tell everyone that you have global redundancy and they won't even bother to damage it because it won't help their cause.

    • donalhunt  3 days ago

      Not all businesses want to pay the premium for that level of redundancy. Businesses with lower margins want resilient service at a lower price point. With AI and contributed shift to cloud, the demand for lowering TCO for a greater share of the larger pie becomes greater.

Update 2:

Upon checking Sentinel-2 imagery for BAH55 from 2026-03-29 to 2026-04-13 (and all later imagery) there is also visible blast damage to the roof of BAH55, which would correspond in timing to media reports about damage caused about 2026-04-01. Sentinel-2 imagery appears to clarify AWS' claim of "while in Bahrain, a drone strike in close proximity to one of our facilities" to mean a direct impact to the building. However it seems likely from high resolution satellite imagery of BAH55 that the machinery rooms of the building perhaps took most of the damage, perhaps leaving data halls in a better shape elsewhere in the building (but possibly still unusable due to water/smoke damage).

It's sad but also interesting that in someone's disaster recovery plan now they need to add a line item about analyzing which datacenters are behind air defenses.
