Super late, but I figured it out because it happened again in a more recent comment. Lemmy seems to automatically change the links to https instead of http, even when http was explicitly included in the url. Somehow, xkcdsw is a completely different site on https than on http. If you copy the link into an external browser and remove the s, the link works as intended. I can only assume this is a behavior of the lemmy app(s), which is why it didn’t affect some users. Were you using jerboa?
I can’t believe it, missed it by a few hours.
How the fuck does this even happen - was the site hacked?
