In its relentless quest for world domination Facebook has seemingly developed the ability to control the weather.
After an air conditioning unit broke down condensation inside their Oregon Data Center formed an actual cloud which began to rain on their servers.
Jay Parikh, Facebook's vice president of infrastructure engineering, told the Register how he couldn't believe what he was hearing when panicked employees rang him.
He said: "I got a call, 'Jay, there's a cloud in the data center'.
"What do you mean, outside?'. 'No, inside'."
"It was raining in the datacenter.
Missing a prime opportunity for all manner of cloud-related puns, the incident, which happened two years ago, was referred to as a "humidity event".
It resulted in a number of servers shorting out and engineers now cover them all with power supplies with rubber "raincoats".
