Probably around 1-2 man-hours directly. The first bit was myself and my coworker running around trying to figure out what this was and how big of a deal after seeing the post on HN. I manually patched a few non-essential systems to make sure the patches took without a huge dependency tree update, then my coworker rolled it out automatically to all the systems.

We spent some follow up time checking Amazon's site to make sure our ELBs were updated (because it wasn't by the time we patched) and sending out the post-mortem to the team. Our certs were already going to expire, so we renewed them and updated them again via automation.
