Supabase Releases Stability Security & compliance

Disk pressure / read-only lockdown

Part of the Database DR & network check

What it is

The database is under disk pressure, or has already been placed into read-only mode because it ran out of space.

Why it matters

In read-only mode every write fails, so the application is effectively down while the database looks up. Growth is rarely linear here — the last few percent disappear faster than the trend suggests.

How to fix it

Free space or increase the disk immediately to clear read-only mode, then find the growth: unvacuumed bloat, a table that never prunes, or logs accumulating in the database. Add an alert well below the ceiling.
