Google says Spectre and Meltdown were the worst vulnerabilities in a decade

Now that the patches across various platforms for the recently discovered Spectre and Meltdown vulnerabilities have largely been deployed, Google has detailed how it managed to address these threats on its cloud services such as Gmail and Search before the public even knew about them. Hint: It wasn't easy. 

In a lengthy blog post Thursday, Google's VP of 24/7 operations Ben Treynor Sloss explains how tough these security holes were to patch, and how long it took Google to fully fix all of them, even though it was Google's own Project Zero team that had discovered them.
