Everyone's thinking it so I'll say it: WTF?!<p>If Wells Fargo turned off online banking for 1 month, I'd switch banks.<p>I wonder if they are handling everything in-house or have hired external consultants/company to build out this wonderful new site & mobile app that will take a full year.<p>Now if their current system had a major exploit and the only way to fix it is to rewrite the whole thing, I guess they have no choice. At the very least they should have put together a temporary "read only" type of site that involve less/no risk on their part and provide their call centers a bit of relief.<p>Ballsy move (and not in a good way.)
