For many (especially in the Northern Hemisphere, where about 87% of humans live), September is the “get back to school” (or work) month after a summer break and that also reflects changes in the Internet traffic, particularly in mobile usage.
Looking at our data (you can see many of these insights in Cloudflare Radar) there’s a global trend: mobile traffic lost importance (compared with desktop traffic) in September. The next chart shows there was less percentage of Internet traffic from mobile devices after Monday, September 6, 2021, with a difference of -2% in some days, compared with the previous four weeks (August), and in late September it’s more than -3%.
We can also see that the percentage of desktop traffic increased in September compared to August (we compare here to complete weeks between both months because there are significant differences between weekdays and weekends).
A few of weeks ago, we saw there are considerable differences between countries regarding the importance of mobile usage. Getting back to work (or office hours) usually means an increase in desktop traffic. In that blog we highlighted the advantages that mobile devices brought to developing countries — many had their first contact with Continue reading
If you’re a regular reader of this blog, you’ve probably realized there’s still need for networking in public clouds, and mastering it requires slightly different set of skills. What could you as a networking engineer to get fluent in this different world? I collected a few hints in the last video in Introduction to Cloud Computing webinar.

Whether you’re just starting in your technology career, or you’re an old hand who likes to go back to basics and understand how to move forward in your career, this episode of the Hedge is for you. Terry Slattery joins Tom Ammon and Russ White to discuss the things you can do to build a successful career as in the world of network engineering.
In this episode of IPv6 Buzz we chat about IPv6 addresses on host OSes: the different types, how they are formed, what they look like, how to tell them apart, and how they are used.

The third quarter of 2021 was a busy quarter for DDoS attackers. Cloudflare observed and mitigated record-setting HTTP DDoS attacks, terabit-strong network-layer attacks, one of the largest botnets ever deployed (Meris), and more recently, ransom DDoS attacks on voice over IP (VoIP) service providers and their network infrastructure around the world.
Here’s a summary of the trends observed in Q3 ‘21:
Application-layer (L7) DDoS attack trends:
Network-layer (L3/4) DDoS attack trends:
A rarely covered topic in technology is professional development. Other careers have extensive programs to ensure practitioners develop and maintain a wide range of skills but this principle is rare in IT.

James Miles sent me a long list of really good questions along the lines of “why do we see so many Internet-related outages lately and is it due to BGP and DNS creaking of old age”. He started with:
Over the last few years there are more “high profile” incidents relating to Internet connectivity. I raise the question, why?
The most obvious reason: Internet became mission-critical infrastructure and well-publicized incidents attract eyeballs.
Ignoring the click baits, the underlying root cause is in many cases the race to the bottom. Large service providers brought that onto themselves when they thought they could undersell the early ISPs and compensate their losses with voice calls (only to discover that voice-over-Internet works too well).
