Today our Heroku hosted app had a meltdown which meant our company couldn't access or use any of our internal tools. This was worrisome to say the least.
After much debugging, it turned out to be Redis that had crashed due to an AWS server crash in the UK... fun times. We only use Redis for actioncable so it seemed really odd that a simple crash of one connected tool would take down an entire app.
Has anyone had an issue like this before and know of a way to mitigate this in the future?
