It seems the addition of file uploads to Cloudflare R2 for DJS contributed to the problem, as the binding of wrangler to R2 was not set properly. We've fixed that, and we're back live.

We deployed a new version that included a major update to wrangler, the tool used to manage our API workers. This failed and led the API to be out of sync with the frontend, locking the app from the API. We're working on a fix.
