Time to accept a new block
Every new Testnet block goes to all three nodes at once. The numbers are how long each node takes to accept it, over the last 24 hours. “Quiet host” counts only blocks that arrived while no other recorded work ran on the machine.

How it works
A Zebra node follows Testnet and hands each new block to the three nodes with submitblock. The three nodes have no peers and empty mempools, so the time is mostly checking and storing the block. They share one machine with other work.
