It looks like the crawler that visits links in posts to collect information to generate link previews doesn’t check that the response is successful (or at least isn’t a 503) and so ends up using the error title.
I see this from time-to-time and as far as I can see it hasn’t been reported before. Example post. To the best of my recollection I’ve only ever seen this with Amazon links and it’s always a 503.

The crawler should abort and retry later.
