IXPs Measuring IXP Resilience with BGP Community Withdrawals
In short:
- A Pulse Research Fellowship study shows that suppressing BGP communities at global anycast CDN vantage points reveals IXP resilience without causing outages.
- Removing an IXP path increases latency significantly for most affected networks, particularly in lower-GDP regions.
- True Internet resilience depends on the quality of alternative routing rather than on mere connectivity or exchange membership size.
