Throughout the year, special events lead to changes in Internet traffic. We observed this with Thanksgiving in the US last week, where traffic dipped, and during periods like Black Friday (November 24, 2023) and Cyber Monday (November 27, 2023), where traffic spiked.
But how significant are these Cyber Week days on the Internet? Is it a global phenomenon? Does e-commerce interest peak on Black Friday or Cyber Monday, and are attacks increasing during this time? These questions are important to retailers and stakeholders around the world. At Cloudflare, we manage substantial traffic for our customers, which gives us a unique vantage from which to analyze traffic and attack patterns across large swaths of the Internet.
As we'll explore next, we observed varying trends. From a global perspective, there was a clear Internet traffic winner: Cyber Monday was the highest overall traffic day of 2023 (as it was for 2022), followed by Black Friday, and then Monday, November 21 from the same week. But zooming in, this pattern didn’t hold in some countries.
For this analysis, we examined anonymized samples of HTTP requests crossing our network, as well as DNS queries. Cloudflare's global data shows that peak request traffic occurred on Continue reading
Special guest David Stengel shares his unique perspective on the cognitive load of platforms in organizations, and the challenges of getting things done even when using tools that abstract workload.

If you’re not paying attention to mDNS traffic, it might be hurting your Wi-Fi performance in a big way. Bryan Ward shares his research looking at the mDNS protocol on a higher ed network and its dramatic impact on Wi-Fi airtime.

As developers, we’ve all experienced times when our code doesn’t work like we expect it to. Whatever the root cause is, being able to quickly dive in, diagnose the problem, and ship a fix is invaluable.
If you’re developing with Cloudflare Workers, we provide many tools to help you debug your applications; from your local environment all the way into production. This additional insight helps save you time and resources and provides visibility into how your application actually works — which can help you optimize and refactor code even before it goes live.
In this post, we’ll explore some of the tools we currently offer, and do a deep dive into one specific area — breakpoint debugging — looking at not only how to use it, but how we recently implemented it in our runtime, workerd.
console.log
. It might be the simplest tool for a developer to debug, but don’t underestimate it. Built into the Cloudflare runtime is node-like logging, which provides detailed, color-coded logs. Locally, you can view these logs in a terminal window, and they will look like this:
Outside local development, once your Worker is deployed, console.log
statements are visible via Continue reading
I am excited to announce that I joined Cloudflare last month as Head of Australia & New Zealand, to continue to build on Cloudflare’s success in the region through extending our valuable relationships with our customers and partners.
I’ve been fortunate over my 25-year career in the IT industry to have worked for some of the most recognised and innovative organisations such as Oracle, Salesforce, and Zendesk. It’s been exciting to be inside these businesses as they’ve taken new ideas about how software can be developed and delivered to solve real world problems for any organisation’s customers. I’ve learned a lot by being a part of the industry, but probably more importantly, I’ve learned the most from the smart, experienced, diverse groups of talented people that I’ve had the pleasure to work with in ANZ and across Asia Pacific. I have always been interested in the problems that organisations are trying to solve through technology — for example, responding to strategic challenges, reducing cost, improving revenue, reducing risk — and joining Cloudflare is an opportunity to stay focussed on addressing those critical issues with our customers and partners using Cloudflare’s innovative solutions.

Forrester has recognized Cloudflare as a leader in The Forrester Wave™: Edge Development Platforms, Q4 2023 with the top score in the current offering category.
According to the report by Principal Analyst, Devin Dickerson, “Cloudflare’s edge development platform provides the building blocks enterprises need to create full stack distributed applications and enables developers to take advantage of a globally distributed network of compute, storage and programmable security without being experts on CAP theorem.“
Over one million developers are building applications using the Developer Platform products including Workers, Pages, R2, KV, Queues, Durable Objects, D1, Stream, Images, and more. Developers can easily deploy highly distributed, full-stack applications using Cloudflare’s full suite of compute, storage, and developer services.
“ A key strength of the platform is the interoperability with Cloudflare’s programmable global CDN combined with a deployment model that leverages intelligent workload placement.”

Workers run across Cloudflare’s global network, provide APIs to read from and write directly to the local cache, Continue reading
It wasn’t that long ago that I wrote a piece about how Wi-Fi 6E isn’t going to move the needle very much in terms of connectivity. I stand by my convictions that the technology is just too new and doesn’t provide a great impetus to force users to upgrade or augment systems that are already deployed. Thankfully, someone at the recent Mobility Field Day 10 went and did a great job of summarizing some of my objections in a much simpler way. Thanks to Nick Swiatecki for this amazing presentation:
He captured so many of my hesitations as he discussed the future of wireless connectivity. And he managed to expand on them perfectly!
Any time I see someone telling me that Wi-Fi 7 is right around the corner and that we need to see what it brings I can’t help but laugh. There may be devices that have support for it right now, but as Nick points out in the above video, that’s only one part of the puzzle. We still have to wait for the clients and the regulatory bodies to catch up to the infrastructure technology. Could you imagine if we did the same Continue reading

George Davitiani put together a lovely proof-of-concept using GitHub actions to deploy modified configurations to network devices. Even better, he documented the whole setup, and the way to reproduce it. I’m positive you’ll find a few ideas browsing through what he did.
