Overlapping signals from independent sources are marked as corroborated; single-signal events stay flagged as uncertain.\n\nMethodology:\n- IODA (Internet Outage Detection and Analysis, Georgia Tech) v2 API: /outages/alerts and /outages/events for entityType country or asn over the look-back window. IODA compares BGP-visible /24 blocks, active-probing responses, darknet telescope traffic and Google/Mozilla traffic against their recent history.\n- Alerts are paired per data source (non-normal alert → next \"normal\" alert) into episodes; an episode without a recovery alert is treated as ongoing.\n- For ASNs (and the ASN hosting a domain's first public IPv4/IPv6 address, via RIPEstat network-info) RIPEstat routing-status gives RIS peer visibility and announced prefixes; bgp-update-activity hours above max(3 × median, 100) updates are flagged as BGP bursts.\n- Domains are also probed directly with one HTTPS GET from this server (reachable = any HTTP response below 500).\n- Intervals from different sources that overlap (30-minute slack) are merged into incidents; ≥2 independent signals = corroborated, otherwise single-signal (could be measurement noise).", "tags": [ "infrastructure" ], "x-mcp-tool": "internet_outage_atlas", "requestBody": { "required": true,
