Appreciate your effort to provide reference info. Near the end it says "part of SoftBank’s efforts to implement robotic automation at [one] Data Center scheduled to start operating [no later than April 1 2027]".
They literally speak of preparing for a future that does not yet exist. I am optimistic it will exist, but that's not the same thing as it already happening and having a track record of reliability and profitability. I could find no mention of robots actually doing anything at that link. The article is about prepping servers, not specifically about robotics, in the same sense that planning hoses for gas pumps at gas stations is not about building cars.
Look at NTT Data or SoftBank.
