CBA says a planned upgrade to its digital banking services is unrelated to a telecommunications failure which hit online banking and card services yesterday.
The Australian bank is shutting down its online and mobile banking services for nine hours overnight to perform essential maintenance.
During this time, customers won’t be able to transfer money, use Pay ID or check their balance, but will be able to use debit and credit cards in stores and to withdraw money from ATMs. However, lower transaction and withdrawal limits may apply.
The timing is inauspicious for the bank, which just yesterday was hit by an outage that affected retail checkout terminals, connections to the New Payments Platform, ATM transactions and a series of online banking services.
This was caused by a glitch at telco Telstra, which also caused processing problems for other major Australian banks.
"We understand the upgrade is happening soon after the telecommunications issue on Thursday, 11 July," states the bank. "This planned upgrade is not related. From time to time we need to upgrade our systems so we can continue to give customers the best banking experience."
