Wells Fargo was in the news for all the wrong reasons last week as a reported fire triggered an outage where customers could not access account; the outage last more than 24 hours for some customers and had people voicing their displeasure on social media; testing for scenarios might be the bank’s biggest issue and not being able to forecast everything forces the bank to make choices; moving to a cloud based system could help to get the bank online quicker, but ultimately only so many scenarios can be tested; when an issue occurs that wasn’t tested the bank needs be transparent and figure out how best to communicate their timeframe about getting back online.
