A bunch of federal websites will shut down with the government, By Andrea Peterson, Washington Post, Published: September 30 at 5:28 pm. Also: The Government Printing Office (GPO) reports:
"GPO will not be updating gpo.gov, FDLP.gov, the Catalog of Government Publications, Ben’s Guide, or be responding to askGPO questions until funding is restored. The Laurel warehouse will be closed so there will be no shipments to depository libraries. Congressional materials will continue to be processed and posted to FDsys. Federal Register services on FDsys will be limited to documents that protect life and property. The remaining collections on FDsys will not be updated and will resume after funding is restored."
Sites that are down include NASA, Library of Congress, Department of Education's ERIC database, Census and USDA. Arstechnica checked 56 .gov sites and found 10 that went dark.
