PS - "Customers of roboadvisers Betterment and WealthFront customers are furious after both companies' servers crashed during today's stock-market route, locking thousands of customers out of their portfolios."
"Wealthfront acknowledged in a statement that its clients lost access to their accounts for “a short period of time today” and said it’s working to make sure “clients don’t experience this again.” Betterment has yet to issue a statement. According to Bloomberg, back during the Brexit fallout in 2016, Betterment told users that it had implemented a “short delay in trading” to protect its users from a “potentially erratic market.” No such statement was issued by the company in this case."
