Once you have the Broken Uplink you will be instructed to take it to the Free States Bunker located in The Mire. The bunker is located far to the northeast of ATLAS Observatory, and directly north of Crevasse Dam. Once you reach the bunker (actually named Abbie’s Bunker) use the Access Terminal to unlock the front door and head inside. Once inside a recording will begin speaking to you, and the quest will be completed.
