Thank you very much for filing this bug! There was a deployment hiccup which I believe I have resolved, and I've noted this deployment glitch in https://bugzilla.mozilla.org/show_bug.cgi?id=1687148#c1 to inform changes to our deployment procedure to avoid this happening in the future.
FYI: We also have a "Searchfox outage" channel on matrix which can also be used for discussing issues, but it's always fine/good to file a bug. (It's just potentially more work for you! ;)
If you refresh, the problem should go away. Note that in ~2 hours there should be a new indexer run that is a proper deployment and based on local VM testing should be fine, but I'll keep an eye on that, but please feel free to re-open if refreshing doesn't fix the issue or you see the issue recur.
