Webhook delivery backlog
A poison message in the delivery queue blocked the head of a shard, delaying webhooks for roughly 9% of customers by up to 41 minutes. No events were lost; all were delivered after the block cleared. We have since added per-message dead-lettering after three failures, which would have contained this to a single event.

Elevated p99 on address screening
A cache invalidation bug caused full re-tracing on repeat lookups of the same address, tripling load. p99 reached 6.4s; p50 was unaffected. Calls that exceeded five seconds were not billed. Fixed by keying the cache on block height instead of a timestamp window.

Tron ingest gap
Two hours of TRC-20 transfer events were ingested late after a node fell out of sync without failing its health check. Scores computed in that window carried a stale as_of_block and were recomputed automatically. Health checks now assert head progression, not just liveness.
