I am skeptical - The host, https://www.burst.net/ Looks like a template monster design with a reseller system, no traffic rank and a nearly empty forum- From a outsider looking in, it looks like a host that is barely in business and likely ran by one guy from his apartment.

Maybe they are over-exaggerating for press? Maybe the server crashed, and they dont want the bad press so did a bogus excuse? Stranger things have happened. But I highly doubt this has even remotely anything to do with "operation in your sites" and is likely related to some issue at burstnet. I wouldnt be surprised if law enforcement isnt even involved.
