Managing modern networks means taking on the complexity of downtime, config errors, and vulnerabilities that hackers can exploit. Learn how BGP Flow Specification (Flowspec) can help to mitigate DDoS attacks through disseminating traffic flow specification rules throughout a network.

Let me tell you something you already know: Networks are more complex than ever. They are massive. They are confounding. Modern networks are obtuse superorganisms of switches, routers, containers, and overlays; a hodgepodge of telemetry from AWS, Azure, GCP, OCI, and sprawling infrastructure that spans more than a dozen timezones.

Just after midnight on October 1, 2023, the remote island of Saint Helena in the South Atlantic began passing internet traffic over its long-awaited, first-ever submarine cable connection. In this blog post, we cover how Kentik’s measurements captured this historic activation, as well as the epic story of the advocacy work it took to make this development possible.

In part 2 of the network observability series, we tackle the first key to the input needed for network observability — from what networks and network elements we gather telemetry data.

CloudWatch can be a great start for monitoring your AWS environments, but it has some limitations in terms of granularity, customization, alerting, and integration with third-party tools. In this article, learn all the ways that Kentik can supercharge your AWS performance monitoring and improve visibility.

With the increasing reliance on SaaS applications in organizations and homes, monitoring connectivity and connection quality is crucial. In this post, learn how with Kentik’s State of the Internet, you can dive deep into the performance metrics of the most popular SaaS applications.

Traditional data center networking can’t meet the needs of today’s AI workload communication. We need a different networking paradigm to meet these new challenges. In this blog post, learn about the technical changes happening in data center networking from the silicon to the hardware to the cables in between.

The goal of network observability is to answer any question about your network infrastructure and to have support from your observability stack to get those answers quickly, flexibly, proactively, and interactively. In this post, Kentik CEO Avi Freedman gives his thoughts on the past, present, and future of network observability.

Businesses are rapidly transitioning to the cloud, making effective cloud cost management vital. This article discusses best practices that you can use to help reduce cloud costs.

In this blog post, we describe how one backbone service provider uses Kentik to identify and root out spoofed traffic used to launch DDoS attacks. It’s a “moral responsibility,” says their chief architect.
