The National Internet Segment Reliability Research shows how the outage of a single Autonomous System might affect the connectivity of the impacted region with the rest of the world. Generally, the most critical AS in the region is the dominant ISP on the market, but not always.

national-stability

National Stability

This metric is based on the average distance from you AS to top-level internet operators (Tier-1) for a selected IP protocol.
A score near of 10 means your AS is very close to these operators, lower rating means the farther distance to the Internet backbone. while a score of near 0 means it's very far. Most networks will be somewhere in between.

score

Connectivity Score

This metric measures the ASN's average distance from the specified AS to Tier-1 ISPs.

tier-1-distance

Tier 1 Distance

This metric shows the count of ASes that are directly connected to your AS.

neighbors

Neighbors

This metric shows the count of ASes that can be considered as Providers to your AS. 
Providers are neighbors who provide transit service to the considered ISP to connect it to the rest of the world.

providers

Providers

This metric shows the count of ASNs that can be considered as Customers to your AS.
Customers are neighbors to whom the considered ISP provides transit service to the rest of the world.

customers

Customers

This metric shows the count of ASNs that can be considered as Peers to your AS.
Peers are BGP neighbors that provide transit services to each other and to their CCs (Customer Cones).
A Customer Cone is a set of Customers, Customers of Customers, and so on.

peers

Peers

This metric shows the count of prefixes advertised by your AS.

prefix-count

Prefix Count

This metric shows the count of ASes in the CC (Customer Cone) of your AS. 
A Customer Cone is a set of Customers, Customers of Customers, and so on.

asn-count-in-cc

AS Count in CC

This metric shows the count of prefixes advertised by ASes in the CC (Customer Cone) of the specified AS.
A Customer Cone is a set of Customers, Customers of Customers, and so on.

Prefix Count in CC

This metric shows average number of hops between peerings limited to specific country

Local is a special filter. When applying it on the specified metric, only ISPs from the specified region will be considered.
Region membership is determined by the country code in the IRR data of the ASNs under consideration.

Local Neighbors

This metric shows the total number of different ASNs of neighboring ISPs that can be considered transit providers of the given ISP.
Providers are neighbors who provide transit service to the considered ISP to connect it to the rest of the world.

Local Providers

This metric shows the total number of different ASNs of neighboring ISPs that can be considered as Customers of the given ISP.
Customers are neighbors to whom the considered ISP provides transit service to the rest of the world.
