Troubleshooting Network Connectivity Issues. Please follow the steps below to diagnose network connectivity issues within Steam: Check Steam Server Status.

Beyond speed tests: Steam performance | SamKnows Our Steam client mimics the behaviour of the real Steam client, by logging into the Steam network, retrieving its local Cell ID, and then looking up a list of available servers and chunks for the cell the user resides in. We made use of an offload server to centrally collate server lists and chunk lists for each cell.

To make connections from behind home NAT's, it uses the libjingle NAT-punching library or, if no direct connection can be made, through the Steam relay servers. The networking functions all live in ISteamNetworking. It's connectionless, using the SteamID's of the users as the destination names.
