Status
Each region as its own nodes report it. A node checks in every 30 seconds. A region counts as up for each 5 minutes one of its nodes did. Nothing on this page is typed in by hand.
Every region
The status couldn't be loaded just now. It comes straight from the control plane, try again in a minute.
Each mark is a day, the newest on the right. Amber was up all day, red had time down, grey has no record yet. A region that doesn't carry NatchPlay relays yet says so rather than reading as down. What TCP and UDP add is the node's own timing of real players' traffic over its last 30 seconds: for TCP from a player's bytes reaching the relay to the tunnel taking them, for UDP the longest any datagram in a batch waited. The middle figure first, then the slowest 1 in 100.
