- aspa/verify: 15min result cache, looking-glass 3s timeout (was 20s default), 5→3 prefixes
- fetchJSON default timeout: 20s→8s prevents all uncached RIPE Stat calls from waiting 20s
- All cards now respond in <1s on cold call (ASPA 200ms, verify 170ms, validate 820ms, WHOIS 50ms)
- bgproutes still 4s cold (bgproutes.io API latency, cached after first call)
Root cause of neighbour=0 for large carriers (AS9002, AS3491, AS12956):
1. RIPE Stat asn-neighbours returns 5000+ entries for Tier-1 carriers,
exceeding the 30s timeout → fetchJSON returns null
2. null was cached in ripeStatCache for 15 minutes (the endpoint TTL)
3. All subsequent requests hit the null cache → perpetual 0 neighbours
Fixes:
- Never cache null results in ripeStatCache (only successful responses)
- Never persist null entries to disk cache
- Increase RIPE Stat timeout from 30s to 45s for prefix/neighbour queries
- Increase RIPE Stat semaphore from 10 to 15 concurrent requests
Verified: AS9002 up=146 down=2702, AS3491 up=90 down=710
- Phase 1: Parse ~400k ROAs from Cloudflare RPKI feed into local store
Eliminates ALL per-prefix RIPE Stat API calls (was 2000+ per lookup)
Binary search validation in <0.1ms instead of 1-20s HTTP roundtrip
Disk persistence (.roa-cache.json) for fast restart
- Phase 2: PeeringDB source cache (L2) for net/netixlan/netfac
6h TTL with LRU eviction (max 5000 entries per type)
Disk persistence (.pdb-source-cache.json) every 30min + SIGTERM
- Phase 3: RIPE Stat semaphore (max 10 concurrent) + response cache
Endpoint-specific TTLs (15min-24h based on change rate)
Max 2000 cached responses, disk persistence
- Phase 4: Extended /api/health with cache status, ASPA adoption metrics
Version bump to 0.6.0
Jittered refresh timers to prevent thundering herd
Graceful shutdown saves all caches
Expected: Audit accuracy 82% -> 95%+, lookup time 90s -> <8s
- Bug 1: Facilities returned ALL 59k PeeringDB entries (missing net_id filter)
- Bug 2: Neighbours returned 0 for large ASNs (8s timeout, now 30s)
- Bug 3: Visibility showed 0% when API times out (now shows -1 = unavailable)
- Bug 4: Prefixes returned 0 for small ASNs (cascading fetch failure)
- Bug 5: RPKI inconsistency documented (different sample sets per endpoint)
- Bug 6: Atlas probe status showed 0 connected (status.name vs status_name)
Also: PDB IX/Fac queries now use net_id (phase 0 + parallel phase 1)
Also: Compare endpoint uses net_id for facilities
- Compare: all API calls in single parallel batch (was sequential)
- Compare: RPKI sample reduced to 3+3 prefixes with 5s timeout cap
- Compare: response caching (5min TTL)
- Compare: AS name resolution parallel with 3s timeout
- Result: Compare from timeout (>20s) to ~5s first call, <1s cached
- Add response caching (5min TTL for lookups, 10min for ASPA)
- Add 8s timeout to all external API fetches
- RPKI validation: sample max 10 prefixes (5 v4 + 5 v6) instead of 50
- Run all PeeringDB + RIPE Stat calls in single parallel batch
- Resolve AS names in parallel with 3s timeout cap
- Add deploy/ directory with production server.js + index.html dashboard
- Landing page: Tokyo Night dark theme, interactive ASN search
- 15 API endpoints: lookup, aspa, aspa/verify, bgproutes, validate,
compare, peers/find, prefix/detail, ix/detail, topology, whois, health
- Features: RPKI per-prefix, RIPE Atlas probes, Network Health Report,
ASPA RFC verification engine, Provider Relationship Graph
