The Starlink Outage and Its Impact on Community Gateways
by Doug Madory
August 18, 2025
Last month, Starlink suffered its largest outage in years, arguably its biggest since becoming a major internet provider. In addition to the millions of individual customers around the world, the outage disconnected the Community Gateways, customers of Starlink’s new transit service. In this post, we delve into the outage and its impact on these far-flung networks.

Data Center VXLAN Overlay Visibility at Scale
by Phil Gervasi
August 13, 2025
VXLAN overlays bring flexibility to modern data centers, but they also hide what operators most need to see: true host-to-host and service-to-service traffic. Kentik restores that visibility by decoding VXLAN from sFlow, exposing both overlay endpoints and underlay paths in a single view without the cost and complexity of pervasive packet capture — the result: faster troubleshooting, smarter capacity planning, and confident operations at scale.

Cloudflare's DNS Downtime: Why BGP Hijacks Were Never to Blame
by Doug Madory
July 31, 2025
On July 14, Cloudflare’s popular public DNS service (known as 1.1.1.1) suffered an outage lasting over two hours. As rumors swirled about the cause, we were the first to push back on the theory that a BGP hijack had caused the outage. In fact, the hijack was actually a consequence. How did we know this so early when other internet watchers did not? We’ll discuss in this post.
