I'm looking for a blog post I read sometime within the past 6 months, if anyone could help.<p>In it, an SRE (I think from Netflix?) visits another company (I think Pinterest or Yelp?) for about a week or so, to just observe and learn from Company B's corresponding team. Company B also sent a similar representative to Company A.<p>The post is largely about comparisons/contrasts/learnings the SRE observed. At some point they make a statement that, if they had to choose only one, they would prefer having comprehensive dashboards reporting live prod statuses over extremely comprehensive testing.<p>I've tried every possible combination of Googling/ HN's search but couldn't find it--anybody happen to know where it is?
