"The email server is down! Users are complaining. I know it's a port issue but can't remember if it's 25, 587, or 993. Need answers NOW."
"Setting up a new service. Which ports need to be open? TCP or UDP? What about security implications? I don't want to break anything..."
"Management is asking for ETA. I'm Googling port numbers while users can't work. There has to be a faster way to troubleshoot this..."
Average cost of system network downtime: $5,600 per minute
