Frequently Asked Questions: BGP Peering, Route Leaks & Subsea Cables
What is a BGP route leak and how does it cause widespread internet outages?
A Border Gateway Protocol (BGP) route leak occurs when an autonomous system (AS) misconfigures routing announcements, propagating IP prefixes learned from one transit provider to another. This inadvertently attracts massive global internet traffic onto bandwidth-constrained links, causing catastrophic packet drops, timeouts, and multi-region service blackouts.
How do subsea fiber optic cable cuts impact global cloud services and ISPs?
Subsea fiber cables carry over 95% of international internet traffic. When optical cuts occur due to maritime anchors, underwater seismic activity, or cable degradation, Tier-1 backbones automatically reroute terabits of data through redundant transoceanic circuits. While Anycast networks prevent total blackouts, users experience elevated latency, bufferbloat, and packet jitter during peak hours.
How does RPKI (Resource Public Key Infrastructure) protect against BGP hijacks?
RPKI is a cryptographic framework that links an IP address block to an authorized Autonomous System Number (ASN) using digital certificates (Route Origin Authorizations or ROAs). Participating Tier-1 transit backbones drop unauthorized route announcements (RPKI Invalid), preventing malicious or accidental IP hijacking.
What is BGP prefix churn and how does IsDownNow detect routing instability?
BGP churn measures the velocity of route announcement and withdrawal updates per minute across global routing tables. Sudden spikes in BGP WITHDRAW messages indicate physical fiber cuts, core router reboots, or Anycast PoP failovers before end users experience app-level outages.
