At 12:01 a.m. Eastern Time on Oct. 1, the US government shut down. In addition to some 800,000 federal employees being furloughed and upwards of a million more being asked to work without pay, several government websites will go dark or not be updated during the shutdown.

According to TIME Tech, the websites for the Library of Congress, NASA, the National Park Service and the Federal Trade Commission have gone dark.

The Federal Trade Commission intends to keep at least six employees from being furloughed to ensure the integrity and security of the agency’s IT infrastructure.

Other websites that are expected to go down are the Federal Election Commission, Department of Veterans Affairs and National Zoo’s Giant Panda Cam.

Congress.gov and Thomas.gov will remain up and functioning.
