The FBI is attempting to track down the identity of the owner of Archive.today and its numerous mirrors, like Archive.is and Archive.ph. As reported by 404 Media, the FBI subpoena, which was posted on the official Archive.today X account, was sent to web domain registrar Tucows on October 30th demanding the “customer or subscriber name, address of service, and billing address” associated with Archive.today.

The subpoena also requests telephone records, payment information, internet session info, network addresses, and even the services the site’s owner has used, such as email or cloud computing services. It goes on to say that this info “relates to a federal criminal investigation being conducted by the FBI,” but it doesn’t reference a specific crime.
