A major bank
I've done some field work for a major bank on both open and mainframe systems.
One day I was called to site after a massive outage only to discover that several of our supported system's had mysteriously panicked and shut down just around 9:00am.
Unfortunately local IT staff where now no longer available and most of the IT heavy lifting was outsourced to another continent so getting clues as to why multiple systems had shut down was difficult. However the biggest clue came from the building contractors who were loitering around the DC waiting on the IT manager. I managed to establish that the contractors had been directed to remove a DC partition wall earlier that morning and all was going well until after 9:00 when a senior manager rushed in and asked them to stop what they were doing and leave the DC. It wasn't until about 1 hour later that they were l sent back in to quickly unwrap the dust sheets they had draped over every single rack in the DC. I never did see the IT manager on that site and I believe he was fired over this along with.
