A severe outage of core payments services at Commonwealth Bank extended into late last night.The trouble flared in the late morning yesterday, leading the closure of an unspecified number of CBA branches - and an emotional barrage on social media platforms.At random times yesterday evening customers reported ability to buy food and otherwise make transfers, though the bank continued to post notices that "We continue to urgently work to restore impacted services as soon as we can." The weight of customer feedback on Twitter suggests the problem was not fixed late last night. By 6am the bank said "network systems are now returning to normal. Our branches will open as per normal today (many until 5pm). ATMs and EFTPOS are operating as normal."
