Is it possible to know who owns the server they are renting with our money?

So YouTube went down in my country, luckily the incident only lasted an hour. But this makes me wonder, who do they rent servers from? Okay, they don't have the budget of YouTube or similar services, but it's... strange to see such a huge contrast between the two. I absolutely don't think it's the developers' fault; I'd rather think it's a problem with their internal management.
