Online trading platforms down for thousands, Downdetector shows

Charles Schwab, Fidelity Investments and Vanguard were among the online brokerages that went down for several hours on Monday amid a global stock market rout.

The reported outages topped 15,000 Charles Schwab users roughly 15 minutes after Wall Street's opening bell, and then dwindled to a negligible number by early afternoon, according to Downdetector.com, a website that tracks outages.

"Due to a technical issue, some clients may have difficulty logging in to Schwab platforms," the brokerage posted on X. The company is working to resolve the problem as quickly as possible, it added.

Outage reports on Fidelity surpassed 3,000, and Vanguard and TD Ameritrade also had thousands of outage reports, Downdetector showed earlier on.

"We are aware some customers may have experienced issues logging in to Fidelity platforms earlier today. This is now resolved. We apologize for any inconvenience," Fidelity posted early Monday afternoon in response to a complaint on social media about its outage. 

Online trading firm Robinhood remained in service Monday.

The reported outages came as U.S. stocks plummeted for a third consecutive trading day, with the Dow Jones Industrial Average dropping more than 1,200 points in early trade, continuing a global selloff sparked by concerns about the economy.
