Almost three years ago, we launched Cloudflare Waiting Room to protect our customers’ sites from overwhelming spikes in legitimate traffic that could bring down their sites. Waiting Room gives customers control over user experience even in times of high traffic by placing excess traffic in a customizable, on-brand waiting room, dynamically admitting users as spots become available on their sites. Since the launch of Waiting Room, we’ve continued to expand its functionality based on customer feedback with features like mobile app support, analytics, Waiting Room bypass rules, and more.
We love announcing new features and solving problems for our customers by expanding the capabilities of Waiting Room. But, today, we want to give you a behind the scenes look at how we have evolved the core mechanism of our product–namely, exactly how it kicks in to queue traffic in response to spikes.
How was the Waiting Room built, and what are the challenges?
The diagram below shows a quick overview of where the Waiting room sits when a customer enables it for their website.
Waiting Room is built on Workers that runs across a global network of Cloudflare data centers. The requests to a customer’s website can Continue reading

Addresses in a Networking Stack
After discussing names, addresses and routes, it’s time for the next question: what kinds of addresses do we need to make things work?
End-users (clients) are usually interested in a single thing: they want to reach the service they want to use. They don’t care about nodes, links, or anything else.
End-users might want to use friendly service names, but we already know we need addresses to make things work. We need application level service identifiers – something that identifies the services that the clients want to reach.

VRF Route Leaking with a FTD
Just had a blast playing with VRF Route Leaking with a FTD. It is so cool and super simple to do. Let’s say you have a Cisco Firewall, a 3140 FTD in this instance, and you want to have varying... Read More ›

Simple or Complex?
A few weeks ago, Daniel posted a piece about using different underlay and overlay protocols in a data center fabric. He says:
There is nothing wrong with running BGP in the overlay but I oppose to the argument of it being simpler.
One of the major problems we often face in network engineering—and engineering more broadly—is confusing that which is simple with that which has lower complexity. Simpler things are not always less complex. Let me give you a few examples, all of which are going to be controversial.
When OSPF was first created, it was designed to be a simpler and more efficient form of IS-IS. Instead of using TLVs to encode data, OSPF used fixed-length fields. To process the contents of a TLV, you need to build a case/switch construction where each possible type a separate bit of code. You must count off the correct length for the type of data, or (worse) read a length field and count out where you are in the stream.
Fixed-length fields are just much easier to process. You build a structure matching the layout of the fixed-length fields in memory, then point this structure at the packet contents in-memory. From there, Continue reading
Heavy Wireless 011: How You Can Participate In The Wi-Fi Awards 2023
The Wi-Fi Awards is an industry effort to recognize excellence and achievements in the wireless community. There are award categories for companies, products, and individuals. Award recipients are determined by a committee and by community votes. Today's Heavy Wireless explores the origins of the Wi-Fi Awards, discusses different award categories and the importance of recognizing individuals. We also discuss the nomination and selection process, and how listeners can nominate candidates.
