Narrative:

I had recently gone on first break as relief officer and was awoken by flight attendants and told to return to cockpit because of fuel gauge problem and that we were diverting. Upon returning to cockpit; captain and first officer told me of problem with fuel quantity gauges and we were returning to ZZZ. ACARS messages were sent to dispatch and maintenance and decision was made to dump fuel. Approximately 7;000 pounds of fuel were dumped. ACARS discussion took place between us and dispatch and maintenance. It was determined we would be overweight for landing. We returned to ZZZ and made uneventful landing.
