Shared redis instances down?

We’re noticing connection issues for the shared redis servers on several apps (exposed on FLY_REDIS_CACHE_URL), but there is no info abut this on the status page.

Also, I can’t seem to find any documentation covering the use of FLY_REDIS_CACHE_URL anymore, is it being deprecated or removed?

Seems like: Please bring Redis back

Upstash is its new not-for-free alternative: Preview: Managed Upstash Redis with read replica support (which is in-preview and not generally available, yet).
