Payments on the bank's NetBank and mobile app did not work on Monday, after it experienced issues across its terminals due to problems faced by its card issuer, Visa.
So I'll assume that we'll have a free money day from @CommBank because they have an outage for like the entire day already? @Telstra gives a free data day when they have an outage so I'll assume CBA will do the same?

The bank said on its Twitter feed on Tuesday morning: "Logins to NetBank and the CommBank app are continuing to operate as normal.
"We're seeing improvements for customers logging into NetBank and the CommBank app.
Pete Steel, executive general manager, Digital, Retail Banking Services, said in a statement that issues at one of the two data centres that supported the bank's mobile app and NetBank caused Monday's problems.

What's the problem?
I've got a trolley full of groceries here at @Coles and I can't pay. I can't access the app either.
I need to transfer money to my sons @CommBank account URGENTLY, now he's unable to get to University.
Steel apologised to customers who had experienced issues logging on to NetBank or the mobile app.
"We have two data centres that support the app and NetBank and unfortunately one of them has had an issue and so there is a lot of demand on one data centre," he said.
"If customers are struggling to log on, I’d encourage them to wait five or 10 minutes and try again. My sincere apologies, and we are working as hard as we can to get the issues fixed."
