Impact of Verizon’s September 30 outage on Internet traffic

On Monday, September 30, customers on Verizon’s mobile network in multiple cities across the United States reported experiencing a loss of connectivity. Impacted phones showed “SOS” instead of the usual bar-based signal strength indicator, and customers complained of an inability to make or receive calls on their mobile devices.

AS6167 (CELLCO) is the autonomous system used by Verizon for its mobile network. To better understand how the outage impacted Internet traffic on Verizon’s network, we took a look at HTTP request volume from AS6167 independent of geography, as well as traffic from AS6167 in various cities that were reported to be the most significantly impacted.

Although initial reports of connectivity problems started around 09:00 ET (13:00 UTC), we didn’t see a noticeable change in request volume at an ASN level until about two hours later. Just before 12:00 ET (16:00 UTC), Verizon published a social media post acknowledging the problem, stating “We are aware of an issue impacting service for some customers. Our engineers are engaged and we are working quickly to identify and solve the issue.”

As the Cloudflare Radar graph below shows, a slight decline (-5%) in HTTP traffic as compared to traffic at the Continue reading

Connection coalescing breaks the Internet

Connection coalescing is the dumbest idea to ever reach RFC status. I can’t believe nobody stopped it before it got this far.

It breaks everything.

Thus starts my latest opinion post.

What is connection coalescing?

It’s specified in the RFC for HTTP/2 as connection reuse, but tl;dr: If the IP address of host A and B overlap, and host A presents a TLS cert that also includes B (via explicit CN/SAN or wildcard cert), then the client is allowed to send HTTP requests directed to B on the connection that was established to A.

Why did they do that?

To save roundtrips and TLS handshakes. It seems like a good idea if you don’t think about it too much.

Why does it break everything?

I’ll resist just yelling “layering violation”, because that’s not helpful. Instead I’ll be more concrete.

Performing connection coalescing is a client side (e.g. browser) decision. But it implicitly mandates a very strict server architecture. It assumes that ALL affected hostnames are configured exactly the same in many regards, and indeed that the HTTP server even has the config for all hostnames.

Concrete things that this breaks:

  1. The server can’t have a freestanding TLS termination layer, Continue reading

Leadership vs Management

Leadership and management these two are often used interchangeably but are they interchangeable? Do we consider all managers to also be leaders and are all leaders managers? While the best managers will have traits of a good leader and visa-versa these two roles are not always synonymous. First thing we will want to do is […]

AI for Network Engineers: Chapter 2 – Backpropagation Algorithm: Introduction

This chapter introduces the training model of a neural network based on the Backpropagation algorithm. The goal is to provide a clear and solid understanding of the process without delving deeply into the mathematical formulas, while still explaining the fundamental operations of the involved functions. The chapter also briefly explains why, and in which phases the training job generates traffic to the network, and why lossless packet transport is required. The Backpropagation algorithm is composed of two phases: the Forward pass (computation phase) and the Backward pass (adjustment and communication phase).

In the Forward pass, neurons in the first hidden layer calculate the weighted sum of input parameters received from the input layer, which is then passed to the neuron's activation function. Note that neurons in the input layer are not computational units; they simply pass the input variables to the connected neurons in the first hidden layer. The output from the activation function of a neuron is then used as input for the connected neurons in the next layer, whether it is another hidden layer or the output layer. The result of the activation function in the output layer represents the model's prediction, which is compared to the expected Continue reading

Wrapping up another Birthday Week celebration

2024 marks Cloudflare’s 14th birthday. Birthday Week each year is packed with major announcements and the release of innovative new offerings, all focused on giving back to our customers and the broader Internet community. Birthday Week has become a proud tradition at Cloudflare and our culture, to not just stay true to our mission, but to always stay close to our customers. We begin planning for this week of celebration earlier in the year and invite everyone at Cloudflare to participate.

Months before Birthday Week, we invited teams to submit ideas for what to announce. We were flooded with submissions, from proposals for implementing new standards to creating new products for developers. Our biggest challenge is finding space for it all in just one week — there is still so much to build. Good thing we have a birthday to celebrate each year, but we might need an extra day in Birthday Week next year!

In case you missed it, here’s everything we announced during 2024’s Birthday Week:

IS-IS Labs: Configure IS-IS Routing for IPv4

In the first exercise in the IS-IS labs series, you’ll configure IS-IS routing for IPv4. The basic configuration is trivial, but you’ll also have to tweak the defaults that most vendors got wrong (we’ll discuss why those defaults are wrong in the next lab exercises).

I also tried to make the IS-IS labs more than just lab exercises. Each exercise includes a bit of background information or IS-IS theory; this one describes generic OSI addresses (NSAPs) and router addresses (NETs).

Git: Set Up a Local Repository Accessible by LAN

A Git repository simplifies the sharing of code to a team. Many teams opt to go the GitHub route but there might be an occasion when you need to spin up a quick repository that is only available to those team members working on your LAN. When you need to deploy a Git repository on your LAN and you need to give other team members access to it, the goal is to do it quickly and securely. Thanks to git and Secure Shell (SSH), this isn’t nearly as challenging as you might think. And although this setup might not be an option for team members who work outside of your LAN, it’s great for a temporary repository offered to those within your company network. How does it work? Let me show you. What You’ll Need To make this work, you’ll need the following: A Linux machine with Git installed. An SSH key pair. A user with sudo privileges (if the minimum requirements aren’t installed). That’s it. Let’s make some Git magic. Installing Git On the off-chance Git isn’t installed, here’s how you can take care of that: Ubuntu-based distributions – sudo apt-get install git -y Fedora-based distributions – sudo dnf Continue reading
