Relayers are addresses signing IBC packets and client updates on this chain. Counts are attempts, not deliveries, and each chain sees its own addresses.
Addresses sharing a label are summed as one operator. Bars relative to the leader. Attempts, not deliveries.
Read from the memo each relayer writes in its transactions; counts addresses, not packets. 11 addresses with no memo are shown as unknown.
9 routes depend on one operator since tracking started: if it stops, packets to that chain stop.
