The Cloud was an Apiaristics Division subfacility containing 99.05% of all human data, encoded in a 3D "cloud" (and its attached control logic) using the holographic principle. The attached picture is of The Cloud shortly after construction: the final Cloud includes an emergency exit for expedient data exfiltration. Due to Incident T80, Cloud data was urgently migrated to Site-26.
It's already far too late.
