We will update this throughout the day.
Update (1:30 p.m. EDT):
The Department of Defense has suspended all intercollegiate competitions at the service academies because of the government shutdown, the Naval Academy said  in a statement posted on its athletics site Tuesday.
The suspension leaves the status of Saturday’s Air Force-Navy football game unclear. A decision on that game will be made by noon on Thursday, the statement said.
Update (12:15 p.m. EDT):
The closure of Smithsonian museums and research centers  is impacting scholars’ access to data and records at those institutions.
Lisa D. Cook, an associate professor of economic and international relations at Michigan State University, is in Washington, D.C. this fall where she is a visiting fellow at the Smithsonian Lemelson Center for Invention and Innovation.
She said the shutdown was forcing her to reorganize her research that had been planned for six to seven months and lamented the lack of access to Smithsonian facilities.
“This is a real loss, since the reason for being in residence is because of the access to experts in this area and to people who have created or maintained these records,” Cook said in an e-mail. “These will be hours, days, and missed encounters I will never be able to reclaim. It also seems to be demoralizing for the researchers on staff whose deadlines and workload will not change, but their ability to meet them will.”
Update (11:30 a.m. EDT):
The Education Department has shuttered the website  of its research arm, the Institute of Education Sciences. Visitors to the site are unable to access to the department's trove of data on colleges and universities available in the Integrated Postsecondary Education Data System known as IPEDS. Would-be college students or parents hoping to use the department's CollegeNavigator website -- which allows consumers and others to compare information about individual colleges -- will also be frustrated.  The Education Department's main Web site will not be updated, but sites relating to federal student aid programs, including the popular site  for the Free Application for Federal Student Aid, will mostly continue operating as normal.
On Capitol Hill, the House subcommittee on higher education has postponed  a hearing scheduled for Tuesday about simplifying student financial aid.
WASHINGTON -- The federal government grinds to a halt today, given Congress's inability to reach a deal on the federal budget before today's October 1 start of the 2014 fiscal year. The implications for higher education are likely to be mild  at the start, but could ratchet up quickly if the disagreement drags on.
Below are the contingency plans for various agencies important to colleges, their students, and their employees:
