In 2018, we launched the Cloudflare Peering Portal, which allows network operators to see where your traffic is coming from and to identify the best possible places to interconnect with Cloudflare. We’re excited to announce that we’ve made it even easier to interconnect with Cloudflare through this portal by removing Cloudflare-specific logins and allowing users to request sessions in the portal itself!
We’re going to walk through the changes we’ve made to make peering easier, but before we do that, let’s talk a little about peering: what it is, why it’s important, and how Cloudflare is making peering easier.
Put succinctly, peering is the act of connecting two networks together. If networks are like towns, peering is the bridges, highways, and streets that connect the networks together. There are lots of different ways to connect networks together, but when networks connect, traffic between them flows to their destination faster. The reason for this is that peering reduces the number of Border Gateway Protocol (BGP) hops between networks.
For a quick refresher, Border Gateway Protocol (or BGP for short) is a protocol that propagates instructions on how networks should Continue reading

Here’s another question from the excellent list posted by Daniel Dib on Twitter:
BGP Split Horizon rule says “Don’t advertise IBGP-learned routes to another IBGP peer.” The purpose is to avoid loops because it’s assumed that all of IBGP peers will be on full mesh connectivity. What is the reason the BGP protocol designers made this assumption?
Time for another history lesson. BGP was designed in late 1980s (RFC 1105 was published in 1989) as a replacement for the original Exterior Gateway Protocol (EGP). In those days, the original hub-and-spoke Internet topology with NSFNET core was gradually replaced with a mesh of interconnections, and EGP couldn’t cope with that.

Whats the deal with Quiet Quitting ? Johna & Greg get into a heated debate about the nature of work. Johna wants people to ‘do your job’, Greg wants ‘pay me more to do more’. How much can a companies expect from their employees as hustle culture is being rejected by more people.

Cloudflare operates in more than 275 cities in over 100 countries, where we interconnect with over 10,000 network providers in order to provide a broad range of services to millions of customers. The breadth of both our network and our customer base provides us with a unique perspective on Internet resilience, enabling us to observe the impact of Internet disruptions. In many cases, these disruptions can be attributed to a physical event, while in other cases, they are due to an intentional government-directed shutdown. In this post, we review selected Internet disruptions observed by Cloudflare during the third quarter of 2022, supported by traffic graphs from Cloudflare Radar and other internal Cloudflare tools, and grouped by associated cause or common geography. The new Cloudflare Radar Outage Center provides additional information on these, and other historical, disruptions.
Unfortunately, for the last decade, governments around the world have turned to shutting down the Internet as a means of controlling or limiting communication among citizens and with the outside world. In the third quarter, this was an all too popular cause of observed disruptions, impacting countries and regions in Africa, the Middle East, Asia, and the Caribbean.
Companies are increasingly adopting managed Kubernetes services, such as Microsoft Azure Kubernetes Service (AKS), to build container-based applications. Leveraging a managed Kubernetes service is a quick and easy way to deploy an enterprise-grade Kubernetes cluster, offload mundane operations such as provisioning new nodes, upgrading the OS/Kubernetes, and scaling resources according to business needs.
AKS also provides a fault-tolerant Kubernetes control plane endpoint and automates the worker node maintenance and deployment process. With regards to networking within the cluster, AKS provides an integrated CNI to address basic Kubernetes networking requirements, such as configuring network interfaces and providing connectivity between pods. However, the basic container networking in Microsoft AKS comes with a limited set of IP addresses. As businesses grow, so does application usage. Having a limited set of IPs can cause scale, availability, and manageability challenges for Microsoft AKS users.
In this blog post, I will discuss IP address exhaustion on Microsoft AKS and how Calico can solve this issue. I will also explore how Calico can address scalability challenges and provide resources that can quickstart your journey in using Calico to solve IP address exhaustion on AKS.
Earlier this year, Microsoft AKS introduced the ability to bring Continue reading
