In March 2018, fifteen months after his initial request, Dehaye finally received an e-mail from Facebook's Privacy Operations Team. He was told that the information he sought "is not available through our self-service tools" but is stored in "Hive," Facebook's "log storage area," where it is retained for "data analytics" and maintained as separate from "the data bases that power the Facebook site." The company insisted that accessing the data required it to surmount "huge technical challenges." "This data," the company writes, "is also not used to directly serve the live Facebook website which users experience."
