The system check measures the connectivity from your computer to Fast Lane lab environment. It doesn't test the connection speed between your computer. Speed can be affected by factors including computer processing power and how busy your network is.

System Check Successful only indicates that the required ports are open and you are able to access the labs via HTTPS and Secure WebSockets.

DE Datacenter 217.110.100.76 (Port 443)
US Datacenter 12.174.134.104 (Port 443)
IN Datacenter 182.18.181.126 (Port 443)

System Check Failed can have several reasons:

1) your local internet connection failed
2) a low level firewall packet inspection or filtering may prevent connection to the lab if the required protocols are not allowed
3) the datacenter internet connection failed

Please contact your trainer if you are not able to perform a successful system check.
