The problem with this mentality is that it does not deter those wishing to do harm to the data centre or corporation. For banks, I think the biggest advantage of having a no-name building is that the general public will not try to enter the building thinking that there is a bank branch or ATMs available and then rudely be thrown out by the guards. If you look at Toronto, the main carrier hotel is quite famous at 151 Front Street, very near to the main train station, convention centre etc (aka: right at the core of the downtown). People who do not know about the internet infrastructure may not realise what this building is about, but anyone who knows how ISPs operate would know the strategic importance of that building. The thing about a carrier hotel is that it cannot be a secret location since you need to allow various carriers and ISPs to have physical access to the building so they can install/manage their servers/routers/switches. The advantage of this swedish data centre is that even if its location is well known, it is pretty hard to harm the building. You can't run a truck full of explosives into it for instance.
