Several US government websites are now inaccessible after TLS certificates expire during the shutdown.
In a government shutdown all that is considered non-essential stops. As we can see now, renewing the TLS certificates is obviously non-essential. Reportedly, more than 80 TLS certificates have expired, leaving dozens of government-related websites inaccesssible. The Department of Justice, NASA and the Court of Appeals are among the sites that have been affected. Important services have been impacted because of this as well, including payment portals.
