Cloudflare patches Copy-Fail across all servers in two days

Corporate Blog

Kind of crazy to look at the graph in this blog. CVE drops on 04/29, they develop a patch on 4/30, and deploy it across all of their servers on 05/01. Obviously they have the engineers to write BPF-LSM patches, but I think it points to a future where they can (almost) keep up with vulnerability disclosures.
