Not following. The recipients received the payments twice. But did the affected business accounts also get debited twice? I'd assume some would have run out of funds or hit a credit line.
I know nothing about how real life banking software works. (I guess I'm glad not to know...) But I'd assume the blance of both affefted accounts are updated in an ACID transaction?
- etothepii 5y agoI know that it is not ACID on debit and credit as I was once transferring £70k between my co-founder and I at £10k per day. For some reason the 5th transaction got credited to my account but not debited from his. We tried to return the money but both banks were adamant that no error had occurred.
- usr1106 5y agoTrue. As soon as more than 1 bank is involved you proably cannot make it always consistent from the point of view of 2 accounts in different banks.
- thenickdude 5y agoInteresting, I wonder if a transaction was accidentally "de-duplicated" on one side. I would experiment further, lol
