Ask HN: What's your most embarrassing moment in IT career?

For me, During my first job as an IT support engineer, everyday I used log into production server as 'root' user and check logs. Few weeks later, intern joined this team, I thought him how to verify production server logs. Few days later, while intern is verifying the log, senior team member saw this and told us "we never had root access to production server, you guys are checking logs from our dev server everyday!"
