I was having intermittent search failures this morning, but now every query results in this error:
Sorry, we ran into an error displaying these results. Click here to try again.
I tried looking for an official status page, but couldn't find one. That said, it looks like others are having the same issue: https://downdetector.com/status/duckduckgo/
EDIT: They've now updated the search results page with the following after it returns no results:
We’re experiencing an outage.
Thanks for your patience while we get our ducks in a row!
Saw the error, immediately typed "duckduckgo status" into the address bar and searched - in DDG.
Not my smartest moment.
