Bungie gives players an in-game banner when they are issuing a restriction that tells you for how long and a general idea of why (whether it was for suspicious behavior or poor network connectivity). This is the only notification you will get from Bungie and if you clicked through that banner there is no way to re-visit it. Players with poor connections will generally receive one warning with no restriction. If they continue to play with the same connection then they will receive a second warning that comes with a 2 week restriction. And after the 2 weeks is up if you continue to play on the same connection your next warning will come with a 2 month restriction. So if you've previously received a 2 week restriction then the current restriction is likely 2 months long. If this is the first actual restriction you recall receiving then odds are it is the 2 week restriction. Be aware, that if your restriction is due to poor Internet then I would strongly suggest you avoid playing Gambit and any Crucible game modes unless you address your Internet performance.
