that's but a blink of the eye
At my last gig, during height of the supply chain strain, we had the arico go out in our main server room. We did our due diligence of opening windows, pinching every fan in the building, strategically placing pinched fans to move as much cooler air as possible. Then the airco engineers came, they spoke with the head of facilities. His entrance to our office, spoke volumes, but the news was worse than let on. There were no spare parts, the unit was EOL'd the previous year*. There were none to replace the unit with our needed specs at the time. Estimated time of delivery 1 week! We rented portable airco units and industrial fans, and limped through the week. After installation, one day after to be exact, it conked out. Facilities manager is furious, the engineers come back, there's no coolant in the damn thing, they fill it again, test it, and once it's blowing cold air again the leave. A week passes and same thing. A week passes and same thing assuring us the found the issue. A week passes and same thing. Fearing they will lose the account**, they send out the senior installation\trouble shooting engineer. Within one cup of coffee, and 10 minutes of checking around, he finds another valve that's not closed properly! He closes the valve, fills the system again and all was well. My ex-colleagues haven't mentioned another outage, I'm still in regular contact ;-}
*This was the second piece of equipment that went EOL, and when we needed service, we got dumb looks instead. Wouldn't sales be interested in warning something was being EOL'd.
**Oh boy, did they lose the account, and I'm sure it wasn't small potatoes. The were responsible for the HVAC for the entire campus, 3 buildings
