Not bad luck, bad design. Same for Gandi, and for the situation you just described.
Drive failures and HVAC failures due to bad power are not "black swawn" events. These are very common problems for DCs, and a good design takes these problems into account.
However, a "bad" design is cheap, and hopefully the savings is passed to the customer.

Hopefully... My dedicated hosting was very cheap, I paid $20 a month.

It's Delimiter, wasn't it? They weren't a very good hosting organization to begin with, but you get what you pay for.
An old highrise is filled with ten thousands of old second hand server blades, floors by floors of equpiment prolifically producing waste heat. A sure recipe for disaster?
Sure!
A wrongly installed fuse at one phase in the building made one phase burn out too early. I saw a picture of an archeological breaker equipment. They fixed that.
However the missing phase destroyed the compressor motors of their cooling systems. Temperature crept up higher and higher. They had to turn off whole floors of servers. When they believed they fixed the problem, they turned on row by row. Renters then frantically tried to copy what they had on the servers and the half repaired cooling system was overtaxed and they had to turn off servers again.
Edit: made some details more specific.
