I'm trying to figure out if the '1' for the last character of the Google 404 error page is deliberate or accidental... pretty funny!!!!11!!1 (not)
I always assumed it was deliberate. Ten years ago !!!!!1112threefour was a thing.
I'm guessing there's an engineer at Google responding to an alert of thousands of users across the world all attempting to load the same non-existent page on their servers.
And since HN is https they don't even get a referer to see where it came from.
