Ok, so we missed a deployment window today. It was for a Spring-based job processor that will support the website by handling fire and forget jobs. Luckily the only fallout will be the twiddling of thumbs tomorrow and a few people inconvenienced. It was close, but the prospect of releasing such a thing without it being fully tested and proven on staging was too much for both our team lead and myself to bear. However, through the course of the afternoon we put the system through a whole bunch of failure scenarios which should mean that Monday's deployment will go better in the light of the knowledge gained and the configs puzzled over.
