How is my school blocking new Internet traffic after midnight?
My school supposedly cuts everyone's connection at exactly 12:00am. Although the network is still there, Windows shows the "no internet" sign when connecting to the network.
However, the strange thing I have been noticing is that although the school wifi blocks new connections (for example connecting to a new website or watching a new video on youtube), it doesn't seem to care about the connections that it already has (for example, it doesn't cut your connection when you are watching an hour-long youtube video).
Also, it doesn't seem to block your connection if you are continuously connected to a VPN, but cuts you off as soon as you disconnect from that vpn, even when you turn your VPN back on.
Does anybody have any idea how this internet connection control works? (if it is used widely and has a name, please tell me) And is there a way to bypass this block without connecting to a VPN?
