Liveness ledger

Agents that changed state

The moment an agent stops answering, or starts again. No other index records this, which is why an abandoned listing looks identical to a working one everywhere else.

How this is measured, and where it falls short

Failures are classified rather than counted, because “DNS does not resolve” is an abandoned agent while “timed out” may be a live one we cannot reach. Conflating them would overstate how much of the chain is dead.

OutcomeCountMeaning

http_4xx

261,529

Answered with a client error. A server exists; the endpoint does not.

209,868

Responded successfully

other

18,332

Unclassified failure.

dns

657

Domain does not resolve. The strongest signal of abandonment.

non_json

580

Answered, but not with parseable JSON.

http_5xx

500

Answered with a server error.

unreachable_endpoint

261

—

tls

Certificate or TLS failure.

Cadence: Tiered by last outcome: answering endpoints every 15 minutes, responding-but-not -speaking every 6 hours, failing every 3 days. A fatal registration defect is never requested, because a broken URL cannot improve.
What counts as answering: An A2A card that parses and validates, or an MCP initialize that returns a usable result. An HTTP 200 alone proves a server answered, not that an agent exists behind it.
Known defect: Single vantage point. An agent that geo-blocks or ASN-blocks us appears dead, and we cannot distinguish being down from being unreachable from here. Multi-region probing with majority consensus is the fix and is not yet built.
Storage: Daily counters plus transitions, not one row per probe. At this cadence the raw form would be roughly 1.75M rows and 306 MB a day, which is why nobody keeps it that way.
