Russian oligarch's financial network crashed thanks to a crank and a cleaner
A chandelier's cleaning mechanism shredded Ethernet cables, taking out an entire floor's WAN and LAN at a rich Russian oligarch's investment firm.
Intelligence analysis by GPT-5.4 Mini
The Register's On Call column shares a support story from a small investment firm managing a Russian oligarch's European holdings. Cleaners triggered a chandelier lift, which mangled hidden network cables and caused a total floor-wide outage.
A building had a fancy lamp that could move up and down so cleaners could wash it. Hidden inside that moving part were internet cables.
When the cleaners used the machine, the cables got caught and torn apart. That was like cutting the office's phone lines, but for computers.
The lesson is simple: if moving parts and cables are placed together carelessly, a normal chore can break the whole network.
Analysis
What happened
Nathan, who worked for a small investment company serving a very rich Russian oligarch, was called in after a strange outage hit the office. The firm had an elaborate foyer with a chandelier mounted on a clockwork system that could lower it for cleaning.
After the cleaners did their work, the network on one floor died completely. Both WAN and LAN were down, which meant the failure was not just local Wi-Fi or a single switch problem. Nathan tried the usual checks first and found nothing obvious.
The hidden fault
He then looked into the chandelier mechanism and found the real culprit: several Ethernet cables had been routed too close to the winch. They had been tangled and shredded by the gears.
That left Nathan with no clean answer about responsibility. He could blame the person who left unprotected cables beside a moving mechanism, or the person who operated the winch without noticing the damage. The article presents it as a classic On Call disaster story: a strange physical setup, a mundane maintenance task, and a very expensive network mistake.
