Cruising at FL250 we received a CAB PR EXCESS CABIN ALT ECAM. We donned our oxygen mask; initiated a priority descent and advised with ZZZ Center. We leveled off at 10;000 feet. I called the Purser to assess the situation in the cabin. The passenger oxygen masks did not deploy. We made the decision to divert to ZZZ and I completed the brief with the Purser and made PAs to the passengers. We landed uneventfully and taxied to the gate.
A319 flight crew reported a pressurization malfunction during cruise. The flight diverted and landed uneventfully.
