1M square feed apparently hold a Yottabyte of data.
You don't need that amount unless you want to store
Anybody wonders why European and other "Rest of the
World" businesses are "lagging" in public cloud

One obvious interpretation is that the on-premise system is skimming and
decoding all traffic, via a mirror port on the switch for instance, building
its own local database that can then be remotely queried. Allows huge local
bandwidth with minimal off-premise access by performing a distributed search
locally. Not a bad tradeoff. Probably a derivative of Room 641a.
Just don't lose that system or allow it to be hacked as it likely has some
interesting keys and technology.
The process described below seems to have actual cross checks and auditing
to guard against overreach and abuse, at least in obvious ways, which is
refreshing compared to the past.
