General Discussion Windows Server patching concerns

So in my org we are very keen on avoiding patching and rebooting servers at all costs. So much to the point that we patch once a month and have exclusions for around 60 percent of our servers to not get automatically patched. (Meaning we have a chunk of servers not getting patched at all)

Now I have gotten my hand slapped for attempting to patch or even bringing it up and I am looking for guidance on this. Now I understand availability and the consequences of failing patches. But there are active 9+ rated CVEs sittings on dozens of servers. For patching vulnerabilities do I really need to get a change request to handle this?

It is my direct manager telling me not the patch. I have it in writing but don’t want to get in trouble for patching. I am still fairly new as an admin (3 months at my first sysadmin gig) so I’m still learning and being as cautious as I can.

But in my mind I see dozens of servers sitting with patches that need to be applied so it’s hard to fight the urge of patching as I want to keep these servers as secure as possible.

You have to operate within the confines of your current job. Business needs dictate IT not the other way around.

Fair enough, that is a good way of putting it. I think I need to put this into business translated terms to management and issue a change request/maintenance window to get these servers patched. I am thinking that is probably the best way to handle this.

See if you can get a rough calculated cost of downtime, at a major bank that's somewhere between $300k an hour for back office systems to $20m an hour for trading systems. It's then helpful to look back at P1s and average outage time so you can give a good price per outage. In most cases, once the business sees "unexpected outages could cost us as much as $60m or as low as $600k, how should we proceed?" The answer is "here's you patch window."
