Compile a list of hosting companies who lease dedicated servers in underground data centers -- 2

I'm interested in leasing dedicated servers in underground data centers that can withstand electromagnetic pulses (EMPs, which can be caused by solar storms or nuclear events). My problem is that most data centers don't offer dedicated servers, but only co-location, often with a 1-rack minimum. A data center will typically have numerous customers who are hosting companies, who in turn offer dedicated servers. Some hosting companies mention on their website the specific data center they're housed in, but most simply state the location, and need to be asked directly which data center they're in. I've found more than a dozen underground data centers, but I'm particularly interested in servers in Helsinki (such as Equinix's HE2 data center), in the UK (such as SmartBunker), Switzerland (such as Deltalis and Swiss Fort Knox), and Copenhagen (where I haven't found any underground DCs yet). There are other locations I'm interested in, but these should be researched first.
