> From an engineering perspective, they track “number of successful stream starts”, instead of percentage of the time 100% of their services are working. That’s a huge red flag. They don’t measure how often 100% or their services are up because perfect uptime is not the goal and is too expensive (if it’s even possible). If an internally facing service being down doesn’t affect a core metric like number of stream starts by customers, then it’s foolish to treat it as needing 99.999% uptime.
