Summary (from https://news.ycombinator.com/item?id=16902208 https://news.ycombinator.com/item?id=16902208 ): > This appears to be an IT failure comparable to the 2012 and 2015 IT failures at the Royal Bank of Scotland. These involved multi-day / multi-week full/partial outages, and multi-million pound fines. > FT: https://www.ft.com/content/9178ef60-46d9-11e8-8ee8-cae73aab7.. https://www.ft.com/content/9178ef60-46d9-11e8-8ee8-cae73aab7.... > Background: TSB is a UK bank. They had a planned 50-hour maintenance window over the weekend (Fri 16:00 - Sun 18:00), to move away from Lloyds's systems (following the "un-merger" in 2013-2014). This went wrong, in what is likely to become a textbook example of an IT failure. From a letter from Nicky Morgan, chair of the UK Parliament's Treasury committee, to TSB CEO Paul Pester: > The reports of unauthorised transactions, access to other customers’ accounts, and failures of in-branch services have all the hallmarks of an IT meltdown. This is yet another addition to the litany of failures of banking IT systems. Potentially millions of customers could be affected by uncertainty and disruption.

Ironically, TSB's parent company issued a press release (in error?) claiming that the migration has been a "success"! http://press.bancsabadell.com/en/News/2018/04/banco-sabadell-successfully-completes-tsb-technology-migration http://press.bancsabadell.com/en/News/2018/04/banco-sabadell...
