Federal Data Center Enhancement Act of 2023

S 933 extends the Federal Data Center Optimization Initiative's deadline until 2026 and updates requirements for federal data centers. It mandates new data centers (established after 2023) to meet minimum standards for sustainability, cybersecurity, uptime (99.9%+), physical security, and reliable power. Federal agencies must prioritize commercial cloud services over custom infrastructure, modernize legacy systems, and report compliance to Congress. The bill requires annual GAO audits to verify agencies meet these standards and maintains a public website tracking agency compliance. This directly affects all federal agencies operating data centers, focusing on modernizing infrastructure while enhancing security and efficiency.
