Narrative:
[I] was operating as first officer. On climb; we experienced a loss in cabin pressure. During initial climb after the transfer of the bleeds it was noticed that the air was not producing the usual amount. The left pack was losing temperature and gaining pressure while the right pack was working fine. The left pack hi press QRH (quick reference handbook) was performed and the left pack was turned off. We notified ATC that our final altitude would have to be FL250 and we continued on. About ten minutes later we suddenly lost our right pack and there was a rise in cabin altitude. We donned our oxygen masks [and requested priority handling] with ATC and initiated a descent down to 11;000 ft. The oxygen masks in the cabin never dropped. We chose [the diversion airport] because it was the nearest suitable airport for landing. ATC vectored us for landing [and] we contacted [the] company over ACARS to tell them the situation. We prepared for landing and I entered the new airport and runways into the landing performance with the weight shown on my mfd (multi-function flight display) and it checked out as good. On approach the captain stated that the plane felt heavy. We landed without incident and taxied to the gate. Later I would find out that we had landed overweight.
