Route leak incident on January 22, 2026
On January 22, 2026, an automated routing policy configuration error caused us to leak some Border Gateway Protocol (BGP) prefixes unintentionally from a router at our data center in Miami, Florida. While the route leak caused some impact to Cloudflare customers, multiple external parties were also affected because their traffic was accidentally funnelled through our Miami data center location.
The route leak lasted 25 minutes, causing congestion on some of our backbone infrastructure in Miami, elevated loss for some Cloudflare customer traffic, and higher latency for traffic across these links. Additionally, some traffic was discarded by firewall filters on our routers that are designed to only accept traffic for Cloudflare services and our customers.
While we’ve written about route leaks before, we rarely find ourselves causing them. This route leak was the result of an accidental misconfiguration on a router in Cloudflare’s network, and only affected IPv6 traffic. We sincerely apologize to the users, customers, and networks we impacted yesterday as a result of this BGP route leak.
We have written multiple times about BGP route leaks, and we even record route leak events on Cloudflare Radar for anyone to view and learn from. To get Continue reading

AI Workloads Have a New Front Door
For years, AI and machine learning workloads lived in the lab. They ran as internal experiments, batch jobs in isolated clusters, or offline data pipelines. Security focused on internal access controls and protecting the data perimeter.
That model no longer holds.
Today, AI models are increasingly part of production traffic, which is driving new challenges around securing AI workloads in Kubernetes. Whether serving a large language model for a customer-facing chatbot or a computer vision model for real-time analysis, these models are exposed through APIs, typically REST or gRPC, running as microservices in Kubernetes.
From a platform engineering perspective, these AI inference endpoints are now Tier 1 services. They sit alongside login APIs and payment gateways in terms of criticality, but they introduce a different and more expensive risk profile than traditional web applications. For AI inference endpoints, ingress security increasingly means Layer 7 inspection and WAF (Web Application Firewall) level controls at the cluster edge. By analyzing the full request payload, a WAF can detect and block abusive or malicious traffic before it ever reaches expensive GPU resources or sensitive data. This sets the stage for protecting AI workloads from both operational Continue reading
N4N047: Virtual Router Redundancy Protocol (VRRP)

Petr Ankudinov made an interesting remark when I complained about how much time I wasted waiting for Cisco 8000v to boot when developing netlab device configuration templates:
For Arista part - just use AVD with all templates included and ANTA for testing. I was always wondering why netlab is not doing that.
Like any other decent network automation platform, netlab uses a high-level data model (lab topology) to describe the network. That data model is then transformed into a device-level data model, and the device-level data structures are used to generate device configurations.

One of the major differences between OSPF and IS-IS is their handling of inter-area routes. Non-backbone OSPF intra-area routes are copied into the backbone area and later (after the backbone SPF run) copied into other areas. IS-IS does not copy level-2 routes into level-1 areas; level-1 areas (by default) behave like totally stubby OSPF areas with the level-1 routers using the Attached (ATT) bit of level-1-2 routers in the same area to generate the default route.
