the triage agent couldn't connect to the threat-intel feed; the lookup step failed

TL;DR

A feed connection failure can be DNS, egress firewall, a changed feed endpoint, an expired feed credential, or the provider being down, and each has a different owner. Work the layers in order from the agent host, confirm which layer breaks, and then make the agent resilient: cache recent feed data locally with timestamps, mark verdicts made on stale cache as degraded, and queue fresh lookups for when the feed returns rather than failing triage outright.

Use this when

• Every intel lookup errors while other agent network calls work, or all fail together.
• The feed provider status page or your network logs show a change at the failure time.

Not for this skill when

• Only one indicator type fails, such as file hashes. That is a feed content or endpoint path issue, not connectivity.
• The feed returns empty results successfully. That is coverage, not connection.

Steps

1. From the agent host, test name resolution and connection to the feed endpoint and record where it stops. Verify: the failing layer is identified.
2. Check the feed credential status and the current endpoint documentation for changes. Verify: credential and endpoint are current, or the needed update is made.
3. Check egress rules for the agent environment if the connection is blocked locally. Verify: the network path is open per policy, with any change approved by the network owner.
4. Add the resilient behaviour: use timestamped cache on failure, flag degraded verdicts, and retry fresh lookups on a schedule. Verify: a simulated feed outage degrades triage instead of stopping it.
5. Restore the feed and confirm fresh lookups flow, then re-check any verdicts made on stale data. Verify: degraded verdicts are refreshed or explicitly accepted.

Variant phrasings

threat intel feed connection failed agent lookup

The feed connection variant.

triage degraded mode cached intel feed outage

The degraded mode variant.

Compatibility: Commercial and open threat intel feeds with API access, agent egress environments.

Why it happens

A single external feed is a single point of failure placed outside your control. Agents that treat it as always-there discover its absence during the largest campaigns, when the feed is most loaded and most needed.

Edge cases / pitfalls

• Multiple feeds with different failure modes are the structural answer; cache is the tactical one.
• Stale intel is still intel if its age is honest. Always carry the timestamp into the verdict.
• Feed credentials expire like all others. Put them in the same renewal tracker.
