"I want it fixed TODAY."

You make a ton of "assumptions" that someone of your self-imposed title of "CyberSecurity professional" shouldn't make. You assume he doesn't have authority to move files around on that server and/or that what he was doing wasn't a legitimate part of his work. You assume he doesn't have authority to reboot the dev server. You assume he didn't consider the implications of doing so in an environment where he works and you don't. You assume that emailing everyone that might need to use the server is required within his environment and within the context of the usage of the server and it's applications. I get your "by the book" attitude but the real world don't work that way. You do the best job can within the confines of what the management allows and expects. Some places do need your level of meticulous detail and others don't. The fact is you don't know. At all. You don't understand what his organization requires or the permissions and latitude his role as admin allows. You don't know the expectation of the management. You don't know what went through this thought processes before restarting the server, as he well could have considered everything you said but didn't feel the need to write it all down in reddit for your supervisory approval. I can imagine you haven't had to work for management that gives less than two shits about "best practices" and wants shit done now. That's fine, as you may be paid far more in more strict organizations. -- This guy restarted the server and got it fixed. No complains or issues. You'd still be waiting on emails 3 days later from people that don't give a shit about your best practices while the server continued to run at a crawl. You really should listen to Parity99 and check yourself as you don't have the required information to be making judgements on the OP. Your lane is where YOU work, not in the industry. The OPs lane is where HE works. Until you are hired to be a consultant for his company, keep to YOUR lane. You could have posted a informative post reminding about best practices, that would have been fine; good reminder for us all. Instead you can with a hostile, judgemental attitude while lacking the information needing to make said judgements. Learn and be a tighter person, bro.
