Personal Developer Instance dev311998 offline (502 Bad Gateway) since 2026-11-09 ~12:10 CET

Hello, my Personal Developer Instance dev311998 (release Australia) has been unreachable since 2026-11-09 around 12:10 CET. The instance URL returns 502 Bad Gateway. In "Manage my instance" the status shows "Offline"; clicking Refresh briefly shows "Refreshing instance…" and then returns to "Offline". I have not released or reset the instance because it holds active project work. Is there a known issue, or can someone restore/wake the instance? Thank you.
