What’s the longest overnight or multi-night grind you’ve had to do for IT work?

My record so far is a full weekend straight. Friday afternoon to Monday morning.

VM server hypervisors we’d just loved all production VMs to, failed, bringing all VMs down. We had to get vendor on the phone and troubleshoot, and I and two other guys had to restore VMs from backups to our old server farm until we could get the new ones fixed with the vendor and rebuilt (their current OS builds were dead in the water and we were about to dump that vendor and platform line a lead balloon). Man that pressure was intense.

That was a loooooong weekend and I was FIGHTING myself to stay awake by the end of it. Thankfully I had biked to work (I lived close by) so didn’t have to drive home to sleep.

They gave me and the other guys a couple comp days (staggered) as a thank you for getting it all fixed. We IT guys all have these occur at some point in our careers.

What’s your record for number of hours worked straight through with barely any sleep, multiple overnights, and such?
