Great question, and thanks so much for sharing your experience at reddit! For static strings, we create resource files and download them directly into your codebase, so your uptime is totally independent of ours once you deploy your app.

For dynamic strings in the database/generated by users, our servers need to be up to receive + handle the translation request, but that will be cached the next time you try to look the translation up.

I'm glad to hear you guys put thought into reliability from the start!
