  • 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.

In some cases, such an incident could lead to massive network degradation across dozens of ISPs. However, it did not. Why? Because some companies install and maintain their filters properly. And even taking into regard the fact that AS15943 is directly connected to Tier-1 ISPs, they didn’t even notice the incorrect routes. They simply never reached Tier-1s, shrinking in size after each hop. READ MORE →

AS263444 Hitting the headline again

Today, on April 22, 2020, in the world of BGP routing, a thing that usually occurs in rare circumstances, happened. A year and 11 days ago, on April 11 2019, we wrote our first incident report about a thing that has never been observed before - a hijack by, with the highest probability, BGP optimizing software. Later that year, in summer, Cloudflare was brutally hit by the same type of incident. And today, a year after the first incident with AS263444 belonging to Open X Tecnologia Ltda, the same autonomous system… no, you guessed wrong. READ MORE →
