From Mock Paper Scissors:
Guys, one of my fellow Silicon Valley exiles sent me some useful information when I was lamenting that we cannot have nice things anymore.
And given how the 4th Reich is disappearing web pages like a common Mafiosi, I thought this might be a useful tool to have in our belts. You see, you can find many of the now-deleted government website with One Simple Trick!
Access historical versions of U.S. government websites from before January 20, 2025 with a simple URL change.
As they say, "GovWayback is a simple tool to quickly access archived versions of government websites from before January 20, 2025 – just add "wayback.com" after ".gov" in any government URL. GovWayback automatically redirects you to that page's archived version from the Internet Archive."
