Nothing has changed then..
I was working as a contractor at the NAB at the time it was outsourced to IBM in 2010. It wasn't long before the first serious outage occurred. It was pretty famous at the time as NAB wholesale couldn't do the overnight inter-bank transfers (NAB wholesale is the hub of all interbank transfers in Australia) so people were not being paid. That one was down to an IBM developer in India pushing an untested, unauthorised change. That was a particularly nasty one, which necessitated a "restore from backup and roll forward all changes from the journal, inspecting every single one manually" style recovery for their core banking platform. It was about as serious as it could get in a bank.
It appears that over the last couple of weeks the latest round of cheap offshore labour that IBM has thrown at the account has not been given a suitable history lesson before being let loose on the production platforms.
