Due to the government shutdown, some government agency webpages are unavailable. If you come across a .gov webpage that is displaying a message that the website is offline due to the shutdown, you can check archive.org's Wayback Machine. Many of the archived versions of government agency websites are still navigable through the Wayback Machine interface.

If you're having trouble accessing government materials, please contact Debbie Krahmer dkrahmer@colgate.edu, the Accessible Technology & Government Documents Librarian, for assistance.

Edit January 22, 2019: Techcrunch has a running list of sites with expired security certificates, or certificates that will expire if the government shutdown continues.
