BGP Labs: Use BGP Communities in a Routing Policy
A previous BGP lab focused on the customer side of BGP communities: adding them to BGP updates to influence upstream ISP behavior. Today’s lab focuses on the ISP side of the equation: using BGP communities in a routing policy to implement RFC 1998-style behavior.

Ask nearly any Internet user, and they are bound to have their own personal list of favorite sites, applications, and Internet services for news, messaging, video, AI chatbots, music, and more. Sum that question up across a lot of users in a lot of different countries, and you end up with a sense of the most popular websites and services in the world. In a nutshell, that’s what this blog post is about: how humans interacted with the online world in 2023 from what Cloudflare observed.
Building on similar reports we’ve done over the past two years, we have compiled a ranking of the top Internet properties of 2023. In addition to our overall ranking, we chose 9 categories to focus on. One of these is a new addition in 2023: Generative AI. Here are the 9 categories we’ll be digging into:
1. Generative AI
2. Social Media
3. E-commerce
4. Video Streaming
5. News
6. Messaging
7. Metaverse & Gaming
8. Financial Services
9. Cryptocurrency Services
Our method for calculating the results is the same as in 2022: we analyze anonymized DNS query data from our 1.1.1.1 public DNS resolver, used by millions of Continue reading
Cloudflare 2023 Year in Review
The 2023 Cloudflare Radar Year in Review is our fourth annual review of Internet trends and patterns observed throughout the year at both a global and country/region level across a variety of metrics. Below, we present a summary of key findings, and then explore them in more detail in subsequent sections.
Key findings
Traffic Insights & Trends
- Global Internet traffic grew 25%, in line with peak 2022 growth. Major holidays, severe weather, and intentional shutdowns clearly impacted Internet traffic. 🔗
- Google was again the most popular general Internet service, with 2021 leader TikTok falling to fourth place. OpenAI was the most popular service in the emerging Generative AI category, and Binance remained the most popular Cryptocurrency service. 🔗
- Globally, over two-thirds of mobile device traffic was from Android devices. Android had a >90% share of mobile device traffic in over 25 countries/regions; peak iOS mobile device traffic share was 66%. 🔗
- Global traffic from Starlink nearly tripled in 2023. After initiating service in Brazil in mid-2022, Starlink traffic from that country was up over 17x in 2023. 🔗
- Google Analytics, React, and HubSpot were among the most popular technologies found on top websites. 🔗
- Globally, nearly half of web requests Continue reading
Why Simple Cloud Computing Architectures May Be Better
There's no shame in sticking with simpler cloud architectures as long as they get the job done. Here's how simpler clouds can deliver better outcomes in certain instances.Interviewing a Network Engineer Using a Single Scenario
I always said that the Trivia Pursuit certification tests (or job interviews) are nonsense and that one should focus on fundamentals.
In a recent blog post, Daniel Dib described a fantastic scenario: using a simple “why can’t I connect to a web site” question, explore everything from ARP/ND to DNS and TLS.
Obviously, you’ll never see anything that sane in a certification test. An interactive interview doesn’t scale (beyond CCDE), and using humans (and common sense judgment) creates potential legal liabilities (there were rumors that had been one of the reasons a talk with a proctor who could flunk you was dropped from the CCIE test).

Drew Conry-Murray published a excellent summary of his takeaways from the AutoCon0 event, including this one:
Most companies want vendor-supported tools that will actually help them be more efficient, reduce human error, and increase the velocity at which the network team can support new apps and services.
Yeah, that’s nothing new. Most Service Providers wanted vendors to add tons of nerd knobs to their products to adapt them to existing network designs. Obviously, it must be done for free because a vast purchase order1 is dangling in the air. We’ve seen how well that worked, yet learned nothing from that experience.
