Blackout Observatory | Public Evidence Dashboard

Neutral reporting

Language reflects observed signals only. Confidence indicators clarify uncertainty.

Reproducible methods

Every view links to evidence hashes, source timestamps, and documented methodologies.

Accessible for decision makers

Clear summaries, printable charts, and policy-focused takeaways.

Routing Disruptions & Throttling Patterns

Routing events are derived from public BGP collectors and cross-checked with latency metrics.

BGP withdrawal timeline

Number of withdrawn prefixes per 30-minute interval.

Routing disruption details

Summary of notable routing anomalies aligned with connectivity drops.

08:30 Withdrawal spike International reachability down 22% sha256:ad3f...18b2

13:55 AS-path churn Upstream path volatility +41% sha256:44bf...90c1

19:10 Isolation event 3 ASNs temporarily unreachable sha256:9d10...ef22

Confidence 0.74 (Medium)

Attribution Summary

Attribution statements are cautious and evidence-linked. Confidence reflects corroboration across sources.

Routing control indicators

Aligned withdrawal spikes and centralized routing signals.

Confidence 0.78

Observed route withdrawals suggest coordinated routing controls affecting international reachability. Evidence points to cooperation among upstream providers, though intent is not inferred.

Evidence chain Hash: 7ad1...c20b

Throttling behavior

Consistent latency variance and throughput caps.

Confidence 0.66

Throughput reductions align with evening hours across multiple ASNs. Patterns are consistent with traffic shaping, but alternatives remain plausible.

Compare to baselines Hash: 1de9...f04b

DNS reliability

Intermittent failures on resolver infrastructure.

Confidence 0.53

DNS resolution failures may be linked to filtering or infrastructure strain. Additional corroboration required before stronger attribution.

Evidence chain Hash: 0b9c...4f21

Evidence-linked data contracts

Every visualization references a structured contract that records source, timestamps, and integrity checks.

Contract: Evidence snapshot

Canonical payload for live-replay and historical panels.

artifact_id: Stable identifier used in all evidence links.
capture_mode: live_replay or historical label.
source_window: UTC start/end timestamps for the measurement window.
confidence_score: 0–1 numeric score plus textual band.
hash_sha256: Integrity hash for artifact verification.

View contract JSON

Contract: Visualization metadata

Reusable structure for charts, tables, and read-only callouts.

viz_id: Stable chart identifier referenced in the dashboard.
title: Accessible label announced to assistive tech.
evidence_refs: Array of evidence artifacts (URI + hash).
confidence_band: Low/Medium/High textual band used in UI.
refresh_policy: Read-only description of replay cadence.

UI Wireframes & Visualization Concepts

Reusable layouts for journalists and policymakers, optimized for clarity and print export.

Wireframe: Daily briefing

Sections: headline, key metrics, live timeline, analyst notes.

Wireframe: Evidence explorer

Filters on left, evidence table on right, export tools on top.

Concept: Attribution confidence ladder

0.0–0.3 Early signal, needs corroboration
0.31–0.6 Multiple sources, still ambiguous
0.61–0.8 Strong alignment across sources
0.81–1.0 High confidence, reproducible

Concept: Evidence chain transparency

Evidence hash + timestamp available for every chart.
Raw data sources linked with license metadata.
Confidence score shows inputs and weighting.

Accessibility considerations

All charts include textual summaries or aria-labels.
Evidence links are keyboard reachable and descriptive.
Color contrast meets WCAG AA for pills and badges.
Read-only state avoids unexpected focus traps.
