This Week in Net: An outage in the UK, the importance of rollbacks for developers, and how we’re hiring!

Welcome to our weekly review of stories from our blog and other sources, covering a range of topics from product announcements, tools and features to disruptions on the Internet. João Tomé is joined by our CTO, John Graham-Cumming.

In this week's program, which is arriving earlier due to the Good Friday holiday in Europe, we start with Cloudflare's view of the Virgin Media outage in the UK. Then, we get a bit technical and go over the root cause analysis and solution for a bug found in Cloudflare's mTLS implementation. We also talk about the importance of our newest announcement, Rollbacks for Workers Deployments, for developers. There’s a deep dive on how we use Oxy (a Rust project) to deploy new versions of long-lived server software while maintaining a reliable experience. We also discuss how we’re hiring worldwide , but specifically in Portugal (remote included).

In our end of show “Around NET” segment we go to Washington D.C., Zaid Zaid, from our Policy and Trust team, talks about the 2023 Summit for Democracy and Project Safekeeping (that serves under-resourced organizations that are vital to the basic functioning of our global communities).
