Description
The WebSocket/HTTP polling fallback for ULTRAPLAN and long-lived cloud sessions logs roughly 147,000 poll-404 events per week after WebSocket disconnects. The full reconnect state machine (reconnect-in-place via same environment ID, or fresh-session fallback) was added after observing that 98% of disconnected sessions never recovered through polling alone — a meaningful production reliability data point.
Key claims
- 98% of disconnected WebSocket sessions fail to recover via polling
