S. 4629 would extend a program to consolidate existing federal data centers; the bill also would require the Office of Electronic Government to establish minimum requirements for new data centers that address their availability and use as well as protections against power failures, intrusions, and natural disasters. The bill provides guidance on the criteria to consider in developing those new requirements. CBO estimates that enacting S. 4629 would have an insignificant effect on direct spending and no effect on revenues over the 2023-2032 period. CBO has not estimated the discretionary costs of implementing the bill. The bill contains no intergovernmental or private-sector mandates as defined in the Unfunded Mandates Reform Act.
