Exploring Internet traffic shifts and cyber attacks during the 2024 US election

Elections are not just a matter of casting ballots. They depend on citizens being able to register to vote and accessing information about candidates and the election process, which in turn depend on the strength and security of the Internet. Despite the risks posed by potential cyberattacks aimed to disrupt democracy, Cloudflare did not observe any significant disruptions to campaigns or local government websites from cyberattack.

Tuesday, November 5, 2024 was Election Day in the United States. It not only decided the next president and vice president but also included elections for the US Senate, House of Representatives, state governorships, and state legislatures. Results confirm that Republican Donald Trump won the presidential election.

In this blog post, we examine online attacks against election-related sites — some of which were notable but none were disruptive — and how initial election results impacted Internet traffic across the US at both national and state levels, with increases in traffic as much as 15% nationwide. We’ll also explore email phishing trends and general DNS data around news interest, the candidates, and election-related activity.

We’ve been tracking 2024 elections globally through our blog and election report on Cloudflare Radar, covering some of the more Continue reading

You Are Paying The Clouds To Build Better AI Than They Will Rent You

Think of it as the ultimate offload model.

One of the geniuses of the cloud – perhaps the central genius – is that a big company that would have a large IT budget, perhaps on the order of hundreds of millions of dollars per year, and that has a certain amount of expertise creates a much, much larger IT organization with billions of dollars – and with AI now tens of billions of dollars – in investments and rents out the vast majority of that capacity to third parties, who essentially allow that original cloud builder to get their own IT operations for close to free.

Joining ISE to Active Directory

Most ISE deployments use a join to Active Directory to be able to query AD groups, perform user lookups, etc. In this post, I’ll join my ISE lab server to AD. First I’m going to create two OUs in my AD, one for users and one for computers. Why not use the default ones? They are containers, not OUs, which means you can’t apply GPOs to them. Additionally, it makes for cleaner separation from the built-in accounts and allows for applying policies that won’t affect them. I’m creating two OUs:

  • iselab users.
  • iselab computers.

This is done by going to Active Directory Users and Computers, then right clicking the AD domain and selecting New -> Organizational Unit:

Give the OU a name and then click OK:

Repeat for the computers OU. You should now be able to see the OUs:

I’m going to create a user named Bob that I’ll be using to test login later. Right click the users OU and then select New -> User:

Enter the name and logon name:

Click Next. Enter a password for the user. As this is a lab, I won’t require that the user changes the password and the Continue reading

Running Routing Protocols over Tunnels

James got confused by a statement made by Hannes Gredler in his IS-IS book:

Things behave really badly if the total IGP cost over the tunnel undermines the total topologies’ cost. What happens next is that the tunnel “wraps” around itself, ultimately causing a meltdown of the entire network.

Let’s unpack that, starting with “Why would you need a tunnel?”

From Python To Go 001. Get Started.

Dear friend,

As mentioned in previous blogpost, I’ve kicked the new series of blog posts related to Go (Golang programming language) and how to pick that up. Originally my idea was just to explain some concepts, pretty much I’ve done back in past with Code eXpress (CEX) for Python. But then I’ve thought through it further and decided to write a side-by-side guide with Python and Go together, exactly as I’ve done before with multi vendor network automation, when started writing about Nokia SR OS and Cisco IOS XR back in 2016.

Do I Need Both Python And Go?

In our opinion, yes, you do need both. Each of these programming languages shines in some areas more than another. And both of them are applicable to network and infrastructure automation. As such, we recommend to study both, but to start with Python as it is easier and at this stage is wider used than Go. So we encourage you to start with our Network Automation Trainings:

We offer the following training programs in network automation for you:

Moving Baselime from AWS to Cloudflare: simpler architecture, improved performance, over 80% lower cloud costs

Introduction

When Baselime joined Cloudflare in April 2024, our architecture had evolved to hundreds of AWS Lambda functions, dozens of databases, and just as many queues. We were drowning in complexity and our cloud costs were growing fast. We are now building Baselime and Workers Observability on Cloudflare and will save over 80% on our cloud compute bill. The estimated potential Cloudflare costs are for Baselime, which remains a stand-alone offering, and the estimate is based on the Workers Paid plan. Not only did we achieve huge cost savings, we also simplified our architecture and improved overall latency, scalability, and reliability.

Table 1: AWS vs. Workers Costs Comparison ($USD)

When we joined Cloudflare, we immediately saw a surge in usage, and within the first week following the announcement, we were processing over a billion events daily and our weekly active users tripled.

Workers Builds: integrated CI/CD built on the Workers platform

During 2024’s Birthday Week, we launched Workers Builds in open beta — an integrated Continuous Integration and Delivery (CI/CD) workflow you can use to build and deploy everything from full-stack applications built with the most popular frameworks to simple static websites onto the Workers platform. With Workers Builds, you can connect a GitHub or GitLab repository to a Worker, and Cloudflare will automatically build and deploy your changes each time you push a commit.

Workers Builds is intended to bridge the gap between the developer experiences for Workers and Pages, the latter of which launched with an integrated CI/CD system in 2020. As we continue to merge the experiences of Pages and Workers, we wanted to bring one of the best features of Pages to Workers: the ability to tie deployments to existing development workflows in GitHub and GitLab with minimal developer overhead. 

In this post, we’re going to share how we built the Workers Builds system on Cloudflare’s Developer Platform, using Workers, Durable Objects, Hyperdrive, Workers Logs, and Smart Placement.

The design problem

The core problem for Workers Builds is how to pick up a commit from GitHub or GitLab and start a Continue reading
