At JUST EAT, we haven't had an embarrassing performance regression that we haven't noticed and put right on the same day we deployed it - for over two years now. We also haven't been taken down by unexpected load.
We have around 150 engineers deploying tens of times a week across around 120 different components in production. In 2014, we pushed more than 800 discrete changes and coped with around 50% more traffic as we grew. Our uptime has… gone up.
We don't have engineers run a performance test before we release have engineers run capacity tests every month or so when we remember to Instead, we do something a bit different...

DoS yourself in production
I have worked in developer teams, an operations team, and been a generalist shipping software for JUST EAT since 2010 (with a few years doing that elsewhere first). I've lived through cultural and technological change and played a role in effecting it. I had a pivotal role in migrating our platform from a datacentre to the AWS cloud - consequently, we now do tens of deployments a week compared to a tens a year. I've automated systems, tests, servers, and in some cases myself. I've touched many parts of the platform and delude myself that I do an OK job at that.
