Our Senior sysadmin is on vacation, and on Wednesday, our licenses for both our email filtering system and our firewall run out.
I was tasked with getting the replacement systems set up, but due to miscommunication and other issues, I didn't have enough time for a proper test run.
So we're going to flip the switch and hope we are still able to log in and receive mail afterwards.
Cause if we aren't, we're forced to pay 30k € for a license renewal after already purchasing the replacements.

This has lead to a resurgence of my ADHD symptoms, and I wasn't able to wind down all weekend.
I've been having a constant fight-or-flight reflex for the past 3 days, but there's nothing to fight or flee from.
