>>>> PS Nobody ever replied to my question of why it would or would not be better to buy the data centers from landlords in US, rather than pay $800 million for someone to take over US business. <<<<
If you owned a datacenter that would bring $20M in a very depressed market, but for which you have an ironclad lease for $10M per year for 20 years, would you sell it? For what price? Pretty much the present value of the lease I'll bet, including termination penalties. Think about it. They leased these things at the top of the market from people who got one HELL of a deal and aren't going to just sell out for peanuts.
