If your network connection is not available through the Binance servers, the first thing that you should check is your own network connection.
Make sure that you have working Wi-Fi (wireless fidelity) or if using the Binance app, make sure that you have a network connection. If these things are functioning correctly, try restarting your device and reconnecting to your Wi-Fi.
If none of these work, try checking the Binance Twitter page to see if they have announced the website being down. If this problem persists, try contacting customer service at +1(833)-584-1149.
