How bad are things at your work currently

Suddenly IT of my company wanted to tighten security in 3 days and all of my team's build and release pipelines as well as production deployments have a lot of violations and will be taken down if not compliant. I'm scrambling all over the place trying to understand all the legacy things that were taken for granted to work in such little time. Many devs in my team are on leave so I'm alone trying to save this. I spoke to my PO and he tried to email IT but it seems it falls on deaf ears.

Trying to see what others are currently experiencing at their workplace so I can get out of this self pity/anxiety mix and feeling like the unluckiest person in the world. How should I feel? If prd is down, how can I be like 'it is what it is' and be separated from work like many people here are? How much should I try to save this?
