How can we combine elements to develop powerful headers and calls to action? How do we use pre-formatted HTML text, and the text element in SVG for precise control over type? How can we optimise

As a large portion of Internet access shifted from office-focused areas, like city centers and business parks, towards more residential areas like suburbs and outlying towns, we wanted to find out just precisely how broad this geographical traffic migration was.


Over the past 6 months, volumetric DDoS attacks decreased by 82%. However volumetric attacks are not gone yet, still peaking as high as 418 Gbps. In this post, we cover the changing attack landscape and how Cloudflare adapts and evolves to keep the internet safe.
