Observed incident recordDetected by RELIASTRA probes

Official status page failure window - CircleCI

Incident 86e16e24-0aa4-4eac-8b89-44f4fa0aeba2 - endpoint status.circleci.com, measured from us-east. Confirming rule: 2 consecutive failed observations counted 2 of them.

Observed window

Every timestamp is a stored field of this record, printed in UTC. The window begins at the first failure the rule counted and ends, for a resolved record, at the observation run whose consecutive successes closed it.

Opened: 21 Oct 2026 15:50:57 UTC
Confirmed: 21 Oct 2026 15:56:02 UTC - the run that made the failure count reach the threshold; this record did not exist before it
Recovered: 21 Oct 2026 16:00:49 UTC
Duration: 9m (from the stored window)

What was measured

The record is a summary of an observation run set. The referenced observation ids resolve to stored probe entries inside the retention window; the detector keeps no second, narrative version of them.

Endpoint observed: Official status page - https://status.circleci.com
Measured from: us-east - the only observation region named in this record; nothing about other regions is claimed or inferred
Failed observations: 2, consecutive through the trigger set
Failure shape: probe timeouts
Observation references: first ab9312c8-3766-4e29-8894-3cdcff328215 last 47f7c9ad-72f4-4b89-af44-3c2fc540138c

The claim, in full

Between 2026-10-21T15:50:57.235353+00:00 and 2026-10-21T15:56:02.553641+00:00, RELIASTRA probes in us-east recorded 2 consecutive failed observations against https://status.circleci.com (the observed CircleCI target). Failure class: timeout; observed status: no HTTP response. This record describes the observed endpoint only and is not a statement about the vendor's services as a whole. That is all of it. Nothing about the vendor as a whole, nothing about other regions, nothing about your requests - the record you are reading is the measurement, not a narration of it.

Evidence artifact

A frozen, hashed document of this record's window: the claim, the detection rule, and every observation row it rests on. Deterministic, reproducible from stored data, immutable once written.

Artifact: /api/v1/public/incidents/86e16e24-0aa4-4eac-8b89-44f4fa0aeba2/evidence - JSON, served byte-for-byte as stored
Content hash: sha256: c2c284ce60e1f6ef0be75770c97896b6b109466c6e197fd7159afd33fe8c957c
Freeze: version 2, taken while the incident was resolved (21 Oct 2026 16:06:59 UTC); later freezes supersede, never edit, and each stays at its own versioned URL
Coverage: 6 observations in the window
Verification: Remove the "verification" key from the document, re-serialise with sorted keys and compact separators, and SHA-256 the UTF-8 bytes: the digest must equal the hash above. The recipe ships inside every artifact.

What this record does not establish

The boundaries are part of the record, not a disclaimer under it.

Causation: Not established. A 5xx can be the vendor, a shared middle path, or the probe's own egress - the record reports what came back, not why.
Vendor acknowledgement: CircleCI may have recorded this window differently, later, or not at all. RELIASTRA does not ingest vendor-reported status, so no reconciliation is offered either way.
Global reach: This window is named for us-east. A record from one observation region never settles the question in another.
Customer impact: Whether your requests were affected is your measurement to make - this record carries only RELIASTRA's own probes.
