Concord will be ending its live service on September 6, 2024.

"Therefore, at this time, we have decided to take the game offline beginning September 6, 2024, and explore options, including those that will better reach our players." - Ryan Ellis, Game Director @ Firewalk Studios

A relaunch means that it's once again playable, as an online multiplayer game, and retains the same name. i.e. not "a spiritual successor to Concord" made by the same or different devs set in the same universe while reusing assets or the like.
