I saw this QR code in the latest episode of Doctor Who and obviously tried to scan it. This fails; the three big squares in the corners should all match, with a smaller filled square inside them. Only two of them are right. Additionally, and you might have to zoom in for this, the smaller square in the fourth corner should also have a little square inside it. So, I edited those in, and it links to...

Which then redirects to https://www.doctorwho.tv/
Stephen Fielding is a graphic designer who has worked on Doctor Who for a few years. His name also appeared in the list of piano students at the beginning of The Devil's Chord (thank you Tardis wiki)
From searching for him, it looks like this is normally his portfolio website, but I can't get any other pages to load. Too much traffic, maybe? The Internet Archive has captures from as far back as 2015 and as recently as 5 o'clock this morning. Perhaps he put that in without anyone realising, and they made him put a redirect in earlier today.
