That wont work. It may bypass some direct tariffs on US soil but it doesnt insulate them at all from broader ripple effects from these tariffs. We live in a globalized market and sweeping tariffs from the largest economy create imbalances in trade that such a relocation strategy wouldnt work, for one simple reason. MS, Sony, Nintendo operate in a global market where different parts are built by different companies from different countries and so is the pricing. ITS dependent on the US economy which is the leading consumer of said services.The tariffs are mostly US related, though. You can build a data center in Canada or Mexico to serve the US market and completely avoid the tariffs.
So global supply chains for data center components and even brick and mortar will be affected by tariffs imposed by the largest economy and it will inevitably drive up costs for everyone since these supply chains rely on the US market to maintain current prices.
Basically a distortion in the flow of goods and services(especially high tech goods) in the US economy even without tariffs would have significant negative effects on building out data centers in Canada or Mexico. Now with sweeping tariffs, relocation is just not going to insulate them. Everyone's going to feel the negative consequences if there are any, especially cloud computing firms or other high tech multinationals like Sony, Nintendo.
