> Is it the legacy rails/mysql stack that is the largest culprit or is there systemic rot in the engineering org? The culprit is change. Infra changes, config changes, new features, system state (os updates, building new images, rebooting, etc...), even fixing existing bugs all are larger changes to the system than most think. It's really remarkable at this point that Github is as stable as it is. It is a testament to the Github team they have been as stable as they are. It's not "rot" it's just a huge system.
