The audit script was flooding RIPE Stat and PeeringDB with unthrottled
parallel requests, causing 429 rate-limits that resulted in auth=0
false negatives (inflating the failure count).
Changes:
- Added threading.Semaphore for RIPE Stat (max 3) and PeeringDB (max 2)
- Added retry logic to _fetch_ripe (was fire-and-forget)
- Increased PDB retries from 2 to 3 with longer backoff (2s, 4s, 6s)
- Increased ASN stagger from 2s to 3s
Results: Accuracy 84% -> 87% (trend: 77% -> 87%, +10%)
