Tenno of all Platforms, Starting at 4 p.m ET today (45 minutes from this post), we are performing some upgrades to our Matchmaking and Presence Servers. We don't expect too much turbulence, but if you find yourself unable to matchmake while our upgrades are in progress, simply relog into the game. We will update this post when the upgrades are complete. See you soon, Tenno!  EDIT: This is complete but we are monitoring!
