As of Dec 12, 2023 at 04:42 PM (eastern?) the Status Page now reports "Merchants may encounter error messages when operating store admin — What happened? Some merchants may experience errors when trying to access/operate the Shopify admin. We are investigating and will keep you updated."

Nothing reported on the status page at this time. Frontend stores seem to be up, but the Admin seems to be down for all stores. Even partners.shopify.com is returning an nginx 504 Gateway Time-out.
