https://www.theregister.co.uk/2019/01/11/government_shutdown_security/ > The IT impact of the ongoing partial US federal government shutdown has begun to show up in the form of degraded computer security. According to internet services biz Netcraft, more than 80 TLS certificates used on .gov websites have expired and have not been renewed. > That's caused a bunch of HTTPS-protected .gov sites to become inaccessible or throw up browser errors. Some websites, such as NIST.gov, have been scaled back due to the funding freeze.
