Routing is one of the most critical operations of the Internet. Routing decides how and where the Internet traffic should flow from the source to the destination, and can be categorized into two major types: intra-domain routing and inter-domain routing. Intra-domain routing handles making decisions on how individual packets should be routed among the servers and routers within an organization/network. When traffic reaches the edge of a network, the inter-domain routing kicks in to decide what the next hop is and forward the traffic along to the corresponding networks. Border Gateway Protocol (BGP) is the de facto inter-domain routing protocol used on the Internet.

Today, we are introducing another section on Cloudflare Radar: the Routing page, which focuses on monitoring the BGP messages exchanged to extract and present insights on the IP prefixes, individual networks, countries, and the Internet overall. The new routing data allows users to quickly examine routing status of the Internet, examine secure routing protocol deployment for a country, identify routing anomalies, validate IP block reachability and much more from globally distributed vantage points.

It’s a detailed view of how the Internet itself holds together.

Q2 2023 Internet disruption summary

Cloudflare operates in more than 300 cities in over 100 countries, where we interconnect with over 12,000 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.

The second quarter of 2023 was a particularly busy one for Internet disruptions, and especially for government-directed Internet shutdowns. During the quarter, we observed many brief disruptions, but also quite a few long-lived ones. In addition to the government-directed Internet shutdowns, we also observed partial or complete outages due to severe weather, cable damage, power outages, general or unspecified technical problems, cyberattacks, military action, and infrastructure maintenance.

As we have noted in the past, this post is intended as a summary overview of observed disruptions, and is not an exhaustive or complete list of issues that have occurred during the quarter.

For technical tools behind the scenes, we use a combination of Ansible and Packer to build Continue reading

GigaIO introduces single-node AI supercomputer

Installation and configuration of high-performance computing (HPC) systems can be a considerable challenge that requires skilled IT pros to set up the software stack, for example, and optimize it for maximum performance – it isn't like building a PC with parts bought off NewEgg.GigaIO, which specializes in infrastructure for AI and technical computing, is looking to simplify the task. The vendor recently announced a self-contained, single-node system with 32 configured GPUs in the box to offer simplified deployment of AI and supercomputing resources.Up to now, the only way to harness 32 GPUs would require four servers with eight GPUs apiece. There would be latency to contend with, as the servers communicate over networking protocols, and all that hardware would consume floor space.To read this article in full, please click here

SD-WAN Deployment Failures 101: Lessons From The Field

SD-WAN is a cost-effective, flexible alternative to traditional MPLS networks, but the high rate of failed deployments indicates that achieving successful implementation is not straightforward. Organizations must be prepared to embrace new experience-driven approaches to network management, such as the need for visibility into unmanaged networks, to deploy SD-WAN effectively.

Is your data center ready for generative AI?

Enterprise adoption of generative artificial intelligence (AI), which is capable of generating text, images, or other media in response to prompts, is in its early stages, but is expected to increase rapidly as organizations find new uses for the technology.“The generative AI frenzy shows no signs of abating,” says Gartner analyst Frances Karamouzis.  “Organizations are scrambling to determine how much cash to pour into generative AI solutions, which products are worth the investment, when to get started and how to mitigate the risks that come with this emerging technology.”To read this article in full, please click here

Network giants unite to fight security risks

A group of industry stalwarts is banding together to help enterprises, services providers and telcos fight cyber foes.The Network Resilience Coalition includes AT&T, Broadcom, BT Group, Cisco Systems, Fortinet, Intel, Juniper Networks, Lumen Technologies, Palo Alto Networks, Verizon and VMware. Its aim is to deliver open and collaborative techniques to help improve the security of network hardware and software across the industry.The coalition was brought together under the Center for Cybersecurity Policy & Law, a nonprofit organization dedicated to improving the security of networks, devices and critical infrastructure. The Center has a broad security mission, but at least for now, it wants the Resilience group to focus on routers, switches and firewalls that are older, may have reached end-of-life vendor support, or have been overlooked for security patching or replacement. To read this article in full, please click here

Preventing Vulnerable Container Deployments with Admission Control

In a previous blog post, Hands-on guide: How to scan and block container images to mitigate SBOM attacks, we looked at how Software Supply Chain threats can be identified and assessed. The severity of these vulnerabilities determine the posture or scan result for an image i.e. Pass, Warning or Fail. The next question is “What can we do with these results?”. To improve the security posture to reduce attacks on your workload we must ensure that workloads have the fewest possible vulnerabilities and layer on configuration security with KSPM, egress controls, and microsegmentation.

In this post we will cover how the scan results can be leveraged to add an additional layer of protection during Deploy Time in application deployment lifecycles.

It’s worth noting that Calico’s Image Scanner is an offline binary which can be run locally. This means the Image Scanner can be baked into any existing Continuous Integration/Continuous Delivery(CI/CD) pipeline. For example, after an image has been built the image can be scanned by the Image Scanner in an Execution Environment. Here checks can be configured to prevent the image from being pushed to a registry should vulnerabilities be detected. This is effectively how image scanning Continue reading
