This is a fascinating story of how one programmer’s deletion of 11 lines of his code wound up breaking the Internet. Yes, we are really that interconnected.

The story of how 28-year-old Azer Koçulu briefly broke the internet shows how writing software for the web has become dependent on a patchwork of code that itself relies on the benevolence of fellow programmers. When that system breaks down, as it did last week, the consequences can be vast and unpredictable.
