Changelog

All notable changes to PeerCortex are documented here.

[0.5.0] — 2026-03-26

Added

  • RPKI-based ASPA detection via Cloudflare RPKI JSON feed — 1,455+ ASPA objects worldwide, cached and refreshed every 10 minutes
  • RFC-compliant ASPA path verification (draft-ietf-sidrops-aspa-verification-14) — upstream/downstream verification, valley detection, AS_SET flagging, per-hop status
  • ASPA Readiness Score (0–100) with four dimensions: ROA coverage, ASPA object existence, provider match completeness, path validation rate
  • Provider Audit — compares RPKI-declared providers vs BGP-detected providers, highlights missing and extra entries with frequency data
  • Network Health Report — 13 automated checks (Bogon, RPKI ROA, Blocklist, IRR, MANRS, BGP Visibility, Reverse DNS, Abuse Contact, Resource Cert, IX Route Servers, BGP Communities, Geolocation, IRR Object) with traffic-light scoring
  • RIPE Atlas probe integration — shows total probes, connected/disconnected counts, and anchors per ASN
  • Route Views as data source and header navigation link
  • bgproutes.io integration — 3,294+ vantage points, RIB queries, ROV and ASPA status
  • RPKI-Declared Providers section — green badges showing providers from the actual RPKI ASPA object
  • Collapsible lists — "Show X more..." for Detected Upstream Providers (limit 10), Missing/Extra in Provider Audit (limit 5)
  • Numerical ASN sorting across all badge lists and tables
  • WHOIS Details endpoint and dashboard card
  • Network Topology endpoint via CAIDA AS-Relationships
  • Peering Partner Finder — /api/peers/find endpoint
  • Prefix Detail View — /api/prefix/detail endpoint
  • IX Detail View — /api/ix/detail endpoint
  • Recent Lookups with localStorage persistence and quick-click badges
  • Network Compare — side-by-side comparison of two ASNs (common IXPs, shared upstreams, overlapping facilities)
  • Copy button on Recommended ASPA Object code block
  • Demo animation (SVG) in README

Changed

  • ASPA detection switched from broken RIPE DB aut-num remarks search to Cloudflare RPKI JSON feed (rpki.cloudflare.com/rpki.json)
  • Upstream providers now resolved with AS names via RIPE Stat AS Overview API
  • Version bumped to 0.5.0
  • Dashboard footer updated with all data sources including Cloudflare RPKI and Route Views
  • Server User-Agent updated to PeerCortex/0.5.0

Fixed

  • Critical: ASPA objects not detected — networks with valid ASPA (e.g., AS8283 Coloclue, AS6830 Liberty Global) were incorrectly shown as "Not Found" because the old code searched RIPE DB remarks instead of RPKI repositories
  • SyntaxError in frontend — CSS routing styles were embedded as a multiline JS string (single quotes don't allow newlines), moved to proper <style> block
  • Double ASN display — provider badges showed "AS1031 AS1031" when AS name wasn't available, now shows clean single ASN with resolved name
  • Empty brackets in ASPA template — provider names showed "()" when not resolved, now omitted or fetched via RIPE Stat
  • Port conflict on startup — multiple PM2 instances caused EADDRINUSE, resolved with proper process cleanup
  • RPKI per-prefix timeout — limited batch size to 10 prefixes with 8s fetch timeout to prevent hanging on large ASNs

Added

  • Initial public release
  • Web dashboard with Tokyo Night dark theme
  • PeeringDB API v2 integration (network profile, IX presence, facilities)
