Traffic anomalies and notifications with Cloudflare Radar

We launched the Cloudflare Radar Outage Center (CROC) during Birthday Week 2022 as a way of keeping the community up to date on Internet disruptions, including outages and shutdowns, visible in Cloudflare’s traffic data. While some of the entries have their genesis in information from social media posts made by local telecommunications providers or civil society organizations, others are based on an internal traffic anomaly detection and alerting tool. Today, we’re adding this alerting feed to Cloudflare Radar, showing country and network-level traffic anomalies on the CROC as they are detected, as well as making the feed available via API.

Building on this new functionality, as well as the route leaks and route hijacks insights that we recently launched on Cloudflare Radar, we are also launching new Radar notification functionality, enabling you to subscribe to notifications about traffic anomalies, confirmed Internet outages, route leaks, or route hijacks. Using the Cloudflare dashboard’s existing notification functionality, users can set up notifications for one or more countries or autonomous systems, and receive notifications when a relevant event occurs. Notifications may be sent via e-mail or webhooks — the available delivery methods vary according to plan level.

Amazon’s $2bn IPv4 tax — and how you can avoid paying it

One of the wonderful things about the Internet is that, whether as a consumer or producer, the cost has continued to come down. Back in the day, it used to be that you needed a server room, a whole host of hardware, and an army of folks to help keep everything up and running. The cloud changed that, but even with that shift, services like SSL or unmetered DDoS protection were out of reach for many. We think that the march towards a more accessible Internet — both through ease of use, and reduced cost — is a wonderful thing, and we’re proud to have played a part in making it happen.

Every now and then, however, the march of progress gets interrupted.

On July 28, 2023, Amazon Web Services (AWS) announced that they would begin to charge “per IP per hour for all public IPv4 addresses, whether attached to a service or not”, starting February 1, 2024. This change will add at least \$43 extra per year for every IPv4 address Amazon customers use; this may not sound like much, but we’ve seen back of the napkin analysis that suggests this will result in an approximately \$2bn tax on Continue reading

Image optimization made simpler and more predictable: we’re merging Cloudflare Images and Image Resizing

Starting November 15, 2023, we’re merging Cloudflare Images and Image Resizing.

All Image Resizing features will be available as part of the Cloudflare Images product. To let you calculate your monthly costs more accurately and reliably, we’re changing how we bill to resize images that aren’t stored at Cloudflare. Our new pricing model will cost $0.50 per 1,000 unique transformations.

For existing Image Resizing customers, you can continue to use the legacy version of Image Resizing. When the merge is live, then you can opt into the new pricing model for more predictable pricing.

In this post, we'll cover why we came to this decision, what's changing, and how these changes might impact you.

Simplifying our products

When you build an application with images, you need to think about three separate operations: storage, optimization, and delivery.

In 2019, we launched Image Resizing, which can optimize and transform any publicly available image on the Internet based on a set of parameters. This enables our customers to deliver variants of a single image for each use case without creating and storing additional copies.

For example, an e-commerce platform for furniture retailers might use the same image of a lamp on Continue reading

Gone offline: how Cloudflare Radar detects Internet outages

Currently, Cloudflare Radar curates a list of observed Internet disruptions (which may include partial or complete outages) in the Outage Center. These disruptions are recorded whenever we have sufficient context to correlate with an observed drop in traffic, found by checking status updates and related communications from ISPs, or finding news reports related to cable cuts, government orders, power outages, or natural disasters.

However, we observe more disruptions than we currently report in the outage center because there are cases where we can’t find any source of information that provides a likely cause for what we are observing, although we are still able to validate with external data sources such as Georgia Tech’s IODA. This curation process involves manual work, and is supported by internal tooling that allows us to analyze traffic volumes and detect anomalies automatically, triggering the workflow to find an associated root cause. While the Cloudflare Radar Outage Center is a valuable resource, one of key shortcomings include that we are not reporting all disruptions, and that the current curation process is not as timely as we’d like, because we still need to find the context.

As we announced today in a related blog post, Cloudflare Continue reading

New Ansible Galaxy

New Ansible Galaxy

For awhile, the Red Hat Ansible team behind the components Ansible automation hub and Ansible cloud automation hub at console.redhat.com have been on a special ops mission to enhance the galaxy_ng code base that serves the aforementioned components to also serve galaxy.ansible.com, with the intention of replacing galaxy.ansible.com with a fresh code base.

Galaxy, a legacy far far away…

The current Galaxy service has been running at galaxy.ansible.com for many years and is hugely successful in the community. It drives and nurtures Ansible adoption by sharing prebuilt Ansible content that solves many automation challenges.

One of the statistics we are most proud of are the contributions of 33,965 individual automation answers by the community in either Ansible Content Collections or Ansible Roles. Some of the top ranking automation content includes AWS, VMware, Linux, and Windows. Community users are able to download content for free, self-supported and interact with authors via GitHub for any further help or enhancements.

• We are excited to announce that the galaxy.ansible.com code base is being updated with a host of exciting new features that the Ansible community can look forward to. Brought to Continue reading

NSX V2T Layer 2 Bridging with NSX-T Projects

When it comes to migration from one infrastructure to another, there are always complexities and risks involved. Finding the most appropriate approach is key to successful delivery of desired outcomes, but depends on the customisations that exist in the current environment and other operational, technical and business features. The technical solution, presented in this post is just a single step in the entire process of migrating workloads from a NSX-V-based environment to a NSX-T-based, which is also enabled with NSX projects.

The overall migration strategy in this use case is “Lift-and-Shift” between two separate environments. The purpose of this post is to outline the steps necessary to perform in order to create Layer 2 bridges between NSX-V and NSX-T environments and potentially do workload migration between the two environments. The products involved are as follows:

NSX-V setup

The NSX-V environment will sometimes be referred as “source” environment. It consists of 2 ESXi hosts, both with NSX-V installed on them and Continue reading

DNS security poses problems for enterprise IT

Attacks related to Domain Name System infrastructure – such as DNS hijacking, DNS tunneling and DNS amplification attacks – are on the rise, and many IT organizations are questioning the security of their DNS infrastructure.Most IT organizations maintain a variety of DNS infrastructure for public services (websites and internet-accessible services) and private services (Active Directory, file sharing, email). Securing both internal and external DNS infrastructure is critical due to a growing number of threats and vulnerabilities that malicious actors use to target them. Unfortunately, very few organizations are confident in their DNS security.Enterprise Management Associates (EMA) recently examined the issue of DNS security in its newly published research report, “DDI Directions: DNS, DHCP and IP Address Management Strategies for the Multi-Cloud Era.” Based on a survey of 333 IT professionals responsible for DNS, DHCP and IP address management (DDI), the research found that only 31% of DDI managers are fully confident in the security of their DNS infrastructure.To read this article in full, please click here

Why Do We Need Source IP Addresses in IP Headers?

After discussing names, addresses and routes, and the various addresses we might need in a networking stack, we’re ready to tackle an interesting comment made by a Twitter user as a reply to my Why Is Source Address Validation Still a Problem? blog post:

Maybe the question we should be asking is why there is a source address in the packet header at all.

Most consumers of network services expect a two-way communication – you send some stuff to another node providing an interesting service, and you usually expect to get some stuff back. So far so good. Now for the fun part: how does the server know where to send the stuff back to? There are two possible answers¹:
