Narrative:

[I] was captain on [this] flight; approximately 90 minutes into the flight and level at fl 290 an ECAM warning message was generated. Fuel act xfr fault. After confirming it was not an immediate action or an ECAM exception and confirming a fault with the transfer of fuel from the additional center tanks I completed the ECAM procedure; which was unsuccessful. As directed by the procedure a descent was made to FL270 and another attempt was made to transfer fuel; with no success. ECAM procedure was then completed and QRH follow up procedures were applied; which included fuel act unusable (321) and ECAM supplemental. After calculating usable fuel on board; dispatch and maintenance operation center (moc) were contacted. With insufficient fuel on board to continue to the destination; and adhering to the QRH directed maximum flight time of 2.5 hours; moc requested; if possible; a diversion to [airport ZZZ]. Dispatch was given fuel on board (fob) and usable fob and concurred with moc to divert to ZZZ. I requested ZZZ weather; new route; fuel burn and amended release. Fas and passengers were advised of diversion; given arrival time and fas were requested to prepare the cabin. Dispatch was advised of landing weight in ZZZ and I accomplished QRH overweight landing procedure; including confirming landing distance required. Flight manual (FM) 1 was reviewed for diversion/overweight guidance. ATC [was advised] and normal landing was accomplished using longest available runway in ZZZ adhering to overweight landing procedures. Required aircraft maintenance log (aml) entries were made upon gate arrival. Flight continued to [original destination] after 90 minute delay at gate.
