I don't know how useful it will be as a case study since an HA/Ops person in (let's say, the US, Canada, AU, western european countries) has access to do things like buy hypervisor capacity or colocation in just about any location. I could go buy colo in Brussels or Panama City or San Diego or Edmonton or Melbourne tomorrow by contacting the right people.

The Russians are much more restricted from doing anything geographically outside of their own borders (for very well justified sanctions reasons), so their limitations are not the same as an HA person in almost any other country. Maybe some Iranian HA/Ops people will be comparing notes with them.

Sometimes there exist data or processing residence requirements that bind you to a specific region (e.g. EU-only). Also, „all AZs in this region no longer exist“ is not on everyone‘s bingo card, this is a good reminder why multi-AZ deployment in the same region may be not enough.

For data center guys this is definitely a case study, because drone attacks are probably on the threat list for everyone now, for various reasons, including domestic terrorism and hybrid warfare. If you want to defend your investment, time to think what covers you from the air.

It's an open question at what point we'll start seeing small fiesty startups that want to sell you a privately owned air defense system for your datacenter roof. The tech to do it is probably far ahead of the regulatory regime to own and operate autonomous small radar+SAM batteries.

It will require some involvement of state, but it is plausible, that critical infrastructure will be required to have this covered and certain big, licensed private contractors may be able to operate air defense systems on such sites (do you smell the money and lobbying effort?).

Also this may influence the design of such data centers. A drone that a paramilitary group can build is not very sophisticated and won’t carry big payloads. Put an outer concrete shell or some better passive defense, and maybe that will be enough.

As a result of some of my work only slightly related to telecom/internet infrastructure, I happened to get on the marketing lists for about six different Chinese companies that will gladly sell you a full size Shahed-136 clone complete with 2 stroke petrol motor. I wouldn't say that small paramilitaries being only able to fly a 5-10kg max size quadcopter with a munition on it into a datacenter is the limit of possible future capabilities. These things are cheaply made in fiberglass molds and look to be dead simple. They're already showing demo videos of them flying around with very low cost ardupilot capable flight controllers.

They even advertise the airframe and motor packages on Instagram....

The DR plan for pros, "I could go buy colo tomorrow by contacting the right people"

		It was clearly meant as an example of the ease of a non-russian company buying geographically-distributed services in the global marketplace, not "I could go buy this with a few docusign signatures and SWIFT wire transfers tomorrow". I am not in the market for colo in Panama City or Melbourne. I don't think it's a bad thing that the russians are hampered by many limitations but whatever lessons their HA people are learning these days are probably very specific to a sanctioned Russia.

		Unironically yes, if you're just a typical B2B SaaS who doesn't have "datacenter getting hit by a literal missile" in your threat model, this coupled with offsite backups is probably the logical DR plan for that scenario.
