What's worse is that they are not dealing with the behaviour of just one app. Random routing probably works best for a certain subset of their customers, maybe even the majority. If they switched to it it's unlikely to have happened without measuring a few different approaches and deciding this gave the best results overall. Unfortunately they have to deal with all of their customers apps, some of whom might have a huge variation in response time, which seems to trigger these issues - it's a complicated topic and one solution might not work for everyone.
