How to read this map

Hazard / signal: Reachability / routing signals
Exposure: Networks and geography
Consequence / vulnerability: Derived outage confidence, never cause

Official/source values remain distinct from MitchellCo derived screening scores or estimates. Derived values are for prioritization and interpretation, not official warnings or predictions.

How to read this map

Signal: RIPE Atlas reachability changes
Exposure: networks and geography
Context: single-collector RIPE RIS BGP UPDATE activity

Source values remain distinct from the MitchellCo derived outage-confidence score. The score is a triage aid, not an official outage declaration.

Where are multiple Internet measurement probes going offline at the same time?

A disconnected RIPE Atlas probe is evidence of a lost measurement vantage point, not proof of a consumer Internet outage. BGP activity is independent routing context and is not treated as a cause.

How the derived score works

Non-official outage-confidence score, 0–100.

For each ASN + ~1° cell, a single disconnected probe is capped at 20, based only on how recent the disconnect is. For clusters with 2+ probes:
recent concentration = min(55, 18 × ln(number of probes))
recency = max(0, 25 × (1 − median disconnect age / 24h))
repeat evidence = min(20, 4 × (probes − 1))

Connected probes are context only and are not required for the score.

Sources, refresh & limitations

RIPE Atlas API: anonymous probe reads. NetWatch fetches disconnected probes first with one region-bounded paginated query and refreshes every 10 minutes. Connected probes are fetched only if that layer is enabled. Only disconnected snapshots are cached in IndexedDB.

RIPE RIS Live: anonymous WebSocket stream. To avoid processing the entire global firehose, NetWatch subscribes to RRC00 only. The displayed value is therefore RRC00 UPDATE messages in the rolling previous five minutes, not all global BGP updates. UI refresh is at most every 10 seconds.

RIPE Atlas probe coordinates are intentionally obfuscated. A probe can disconnect because of ISP failure, local power/LAN failure, maintenance, hardware failure, or other causes.
