Technology

Kentik's Network Observability Cloud is a software-as-a-service (SaaS) product that ingests NetFlow and other network data and analyzes it to provide network monitoring and anomaly detection services for the operators of Internet-connected networks. Kentik's underlying data engine is a clustered datastore modeled on Dremel.^[5] The engine collects and correlates live operational data from Internet routers and switches to produce network activity and health information.

Analysis

Since November 2020, Kentik has been the organizational home of Doug Madory's Internet routing analysis practice, previously associated with Renesys and Renesys' subsequent acquirers DynDNS and Oracle. While employed by Kentik, Madory discovered the Global Resource Systems IP address hijacking which occurred during the final hours of the Trump administration^[6][7][8][9] and was the first to accurately quantify the 2021 Facebook outage, the largest communications outage in history.^{[10][11][12][13][14][15]}
