A320 flight crew experiences an air engine 1 bleed fault ECAM at FL370. Three minutes later an air engine 2 bleed fault ECAM occurred resulting in both engine bleeds faulted/closed and the cabin pressurization compromised. During descent cabin altitude reaches 9;500 ft and the number one engine bleed is restored successfully; restoring pressurization and the flight continues to destination.

Narrative:
A normal departure and climb out to FL370 was performed. At FL370 an air engine 1 bleed fault ECAM occurred. The A320 ECAM and then FM irregular procedure was followed. One minute later engine 2 fire loop a fault ECAM occurred which was noted as part of a maintenance deferral and the ECAM was cleared. Two minutes after that an air engine 2 bleed fault ECAM occurred resulting in both engine bleeds faulted/closed and the cabin pressurization compromised. An immediate descent was requested from center requiring a 30 degree right turn for traffic separation and an initial descent clearance to FL320. The cabin altitude passed 9;500 ft and engine 1 bleed was cycled to attempt to restore cabin pressure and was successful. Flight leveled at FL320 and continued to destination without further issues other than further engine 2 fire loop a fault ECAM occurrences per the deferral item. Log items were sent to maintenance and a phone call to describe the fault sequence was made following arrival.
