The authorities apparently got tired of asking and just went in themselves.
Canada-based Windscribe, a VPN provider, just said that one of its European servers has been allegedly seized by Dutch authorities without a warrant. According to the company’s post on X, law enforcement said that they will return it to the service provider after they “fully analyze it.” It’s unclear why law enforcement impounded just a single rack from Windscribe’s cabinet, but the VPN provider said that it only uses RAM disk servers, meaning anyone who would look through the installed SSDs would only find a stock Ubuntu install on it, so the servers shouldn’t hold any trackable data.
Police have UPS-like devices which splice into existing mains cables to keep machines alive on the way into the forensics lab. Presumably it’s standard practice to use those.
Of course, the server could be configured to wipe itself if it loses connectivity for more than a few seconds, or its routing changes. The police would need devices that route Ethernet traffic over 5G, though those would presumably be detectable as bandwidth goes down and latency goes up.
