This reminded me of something too! I used to work(on backend) on a popular app(in my country) which had a good number of users. One day I was asked to work with some infra/sysadmin folks who wanted to fix some issues with the servers in our inventory. We happily updated kernels and even rebooted servers a few time. I came back to my team and saw them deeply engrossed into production logs. Turns out few of the servers that were "fixed" were actually production servers. I almost shouted the F word when I listed all IPs. This confusion happened because the server guys used data IPs and we used management IPs. This exposed serious miscommunication among our teams. But fun times indeed!
