   Root cause identified: No actual PGW session failure. During the Sydney Sparkle outage at ~19:00 UTC, Australian devices were temporarily routed through Ashburn LBO proxies. Once Sydney recovered, these sessions became stale. The proxy session drop 12 hours later was automatic TTL cleanup of these orphaned sessions. No action required.
