An Autonomous System Number (ASN) is a globally unique identifier assigned by regional internet registries (such as ARIN, RIPE NCC, APNIC) to a network or collection of IP prefixes operated under a unified administrative policy. Autonomous Systems use Border Gateway Protocol (BGP) to exchange routing information with other networks to form the global internet.
Route flapping occurs when an Autonomous System repeatedly advertises and withdraws its IP prefixes in rapid succession. This triggers BGP dampening algorithms across global core routers, causing traffic destined for that network to be temporarily dropped or rerouted across congested transits, resulting in widespread connectivity blackouts.
IsDownNow continuously merges real-time edge latency probes, multi-region synthetic pings, and incident corroboration feeds. When an Autonomous System exhibits elevated packet loss or latency anomalies consistent with prefix withdrawals, our routing health indicator reflects the route churn in real time.
