State of Colorado Datacenters got them. The response to them were weird...if any machine were in any of the affected areas, they were persona non grata...they could never leave those datacenters as functional server.

It DID lever some money for an awesome off-site backup datacenter...which was eventually our only datacenter for 'reasons'.

In our case, I think one of the datacenter's raised floors got carpeted (don't judge, it predated me, I was equally baffled) and a grounding issue caused a voltage drift causing the tin to migrate...

raised floors in general are a nightmare for grounding/bonding/differences in potential between racks, the steel floor structure, the building, and electrical conduits.

there's a reason why almost nobody builds them new from a clean-sheet-of-paper design anymore for serious datacenter applications or ISP/telecom purposes, which are racks/cabinet on concrete slab and everything overhead now.

it's much easier to ground/bond everything together using some very fat copper cables run along ladder rack overhead, and bond all the racks to that.

Raised floors where a great way to create laminar flow for clean rooms. I suspect that as with manufacturing, the "clean" space is inside the computers now.
