It is a teeny increase, but in recent weeks Cloudflare Radar now shows #IPv6 crossing the 40% proportion threshold in traffic. It has been hovering at 39% for awhile. We'll just have to wait and see if that is the new floor.

We've also extended bot traffic visibility on Radar to support sub-national filters.
Radar now shows bot traffic trends and which networks generate the most bot traffic from your state/region.

Iran is currently enduring its longest-ever internet shutdown, which began shortly after the Feb-28 airstrikes.
My latest post covers all of 2026, outages within the whitelisted traffic, and other observations from our data. #DigitalBlackOutIran

🌍 Small i18n improvement: If you are using Radar in a language other than English, we now display translated geolocations (geonames alternate names) where available. For example, see radar.cloudflare.com/pt-pt/traffi... or radar.cloudflare.com/ja-jp/traffi...
Speed test results are now shared between speed.cloudflare.com and radar.cloudflare.com/speedtest.
Detailed results are shown on Speed, while summary and country/network comparisons are shown on Radar, and users can now easily switch between the two views.
Now I’ll have to check out the new location.
