> **Detecting Peering Infrastructure Outages in the Wild**

> Peering infrastructures, namely, colocation facilities and Internet 
> exchange points, are located in every major city, have hundreds of 
> network members, and support hundreds of thousands of interconnections 
> around the globe. These infrastructures are well provisioned and 
> managed, but outages have to be expected, e.g., due to power failures, 
> human errors, attacks, and natural disasters. However, little is known 
> about the frequency and impact of outages at these critical 
> infrastructures with high peering concentration.

> In this paper, we develop a novel and lightweight methodology for 
> detecting peering infrastructure outages. Our methodology re- lies on 
> the observation that BGP communities, announced with routing updates, 
> are an excellent and yet unexplored source of information allowing us 
> to pinpoint outage locations with high accuracy. We build and operate 
> a system that can locate the epi- center of infrastructure outages at 
> the level of a building and track the reaction of networks in near 
> real-time. Our analysis unveils four times as many outages as compared 
> to those publicly reported over the past ve years. Moreover, we show 
> that such outages have signi cant impact on remote networks and 
> peering infrastructures. Our study provides a unique view of the 
> Internet’s behavior under stress that often goes unreported

> The Internet is transitioning from a hierarchical structure to a flat 
> structure where more and more networks participate in public peering 
> at IXPs and private peering at interconnection facilities to increase 
> performance and reduce transit costs. PeeringDB is a public online 
> database containing information about IXPs, facilities, and networks 
> participating at IXPs and facilities. In this paper, we perform an 
> in-depth analysis of the PeeringDB data to gain an understanding of 
> the public and private peering ecosystems in the five regions of the 
> world (i.e., North America, Europe, Asia Pacific, Latin America, and 
> Africa). We study how IXPs, facilities, and peering networks are 
> distributed across the five regions. We also investigate how 
> distribution of network business type, peering policy, and traffic 
> level varies across the five regions. Our analysis provides a snapshot 
> of the current state of the peering ecosystems in the five regions of 
> the world and reveals the similarities and differences between these 
> peering ecosystems.
