A massive archive of 3.8 million declassified US government files, known as The Black Vault, was mysteriously wiped hours after former President Donald Trump ordered the Pentagon to release all UFO-related documents.

Axar.az, citing Daily Mail, reports that The Black Vault, run by researcher and ufologist John Greenewald Jr, had its main server reportedly wiped clean on February 20, deleting hundreds of gigabytes worth of files on UFOs, declassified CIA projects, and major conspiracies, including the assassination of JFK.

Greenewald shared the news online, explaining that some server directories had their permissions, the safeguards on who can access or edit them, and the file ownership logs changed without explanation.

Luckily for The Black Vault, Greenewald revealed that all of the more than 3.8 million files were backed up in secure locations and the site was restored soon after the mysterious wiping took place.
