Sounds like SRE are fixing bugs and introducing tools and processes that improve reliability.

> There are two main types of reliability work. The first is mitigation, which is a linear fix that’s often referred to as firefighting...The second is change management, which is a non-linear fix that proactively reduces the defect rates through projects like migrating to better tools and refactoring spaghetti code. While SREs support both these types of work, they should spend more time on the latter.
