Degraded Wireless Data Sessions - IMSI 1 - Sydney

We are experiencing degraded wireless data sessions for IMSI 1 subscribers roaming through our Sydney site. Affected subscribers may experience intermittent data connectivity or session drops. The root cause has been identified as GTP echo timeouts from an upstream roaming partner, causing automatic session resets. Sessions are gradually rebuilding as devices re-attach. Our team is actively monitoring recovery and has engaged the upstream partner for investigation.
