  • AS Relation Model

    Our portal represents various analytical data regarding the relation types between autonomous systems (AS). For each AS we openly display its current links as well as the dynamics of their changes. This information is updated daily.

  • Radar Monitor

    Our monitoring system allows detection of a wide range of network anomalies which may have a significant impact on the end-point network resource availability. Currently we provide the information about detected static and dynamic routing cycles, Route Leaks, DDoS amplifiers and bots. The details on the detected incidents are available for technical representatives of the given AS.

  • AS Rating

    In order to simplify the process of comparing different AS our portal provides a set of ratings which let the user perform comparisons by various parameters. For user convenience we have added the search function which makes evaluation of a certain AS in the list a lot easier.

The 2020 National Internet Segment Reliability Research

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

As the number of alternate routes between AS’s increases (and do not forget that the Internet stands for “interconnected network” - and each network is an AS), so does the fault-tolerance and stability of the Internet across the globe. Although some paths are from the beginning more important than others, establishing as many alternate routes as possible is the only viable way to ensure an adequately robust network.

The global connectivity of any given AS, regardless of whether it is an international giant or regional player, depends on the quantity and quality of its path to Tier-1 ISPs.

Usually, Tier-1 implies an international company offering global IP transit service over connections with other Tier-1 providers. Nevertheless, there is no guarantee that such connectivity will be maintained all the time. For many ISPs at all “tiers”, losing connection to just one Tier-1 peer would likely render them unreachable from some parts of the world.
