Route leaks
No route leaks detected in this period.
Hijack — a network announces address space that belongs to someone else. Route leak — a network re-announces routes it learned from one provider or peer to another, so traffic takes a path it shouldn't. Confidence 8+ is high; low scores are often legitimate changes such as a new upstream or a DDoS-protection service.
