I'm a developer, tech support for my extended family, and admin for a bunch of web stack boxes. Is there a guide on what I (or everyone else) should be doing to mitigate this? Or are the steps that need to be / can be taken immediately only at the ISP level? From the comments on the article it seemed like there was even still some disagreement on quite what to do.
