pub static ROUTING_RESOLUTION_SURB_TIMEOUTS: AtomicUsizeExpand description
Cumulative count of outgoing packets dropped because their return route still had no SURB when the resolution wait ran out.
Separate from ROUTING_RESOLUTION_FAILURES because it means something different and
actionable: a counterparty has stopped replenishing SURBs and is not coming back, rather than a
route that could not be computed. A non-zero and growing value names the condition that used to
stall a node’s entire egress indefinitely.
