In my work, I don't deal with Internet traffic too much, so internal packet loss is mostly a sign of poor provisioning or technology (if it is the network's fault) or poor programming (if it is the endpoint's fault). Both of those are fixable. It is very rare to have true congestion and sometimes impossible (if it is a dedicated subnet with only a couple hosts).

For us latency is more important that throughput, so our needs don't match Google's. There are a lot of cases like this.
