The site was down from about 6:30 a.m. to 8:20 a.m. PT today. Frustrated customers told CNET News.com that Schwab's site didn't let users access real-time quotes, check account information and margin balances, or make trades.
One angry client wrote in an email: "I can't take it anymore! 7:30 a.m. and I cannot even access my online account. I have $150,000 in the account and Schwab has another 'outage.' "
According to Schwab spokesman Dan Hubbard, the site was down for almost two-and-a-half hours Wednesday. On Thursday, it was down for about 50 minutes only to those who use the AOL Internet connection.
The site failure Wednesday marked the first such August 30 for Schwab, which had began its after-hours trading services that day. Over the year, Schwab has had at least a dozen outages, according to Hubbard.since
The company said that the cause of the outage wasn't immediately known, though the rest of the site was currently working and customers could place trades by telephone or in person for the same price as on the Web during the outage.
When asked if the company was taking measures to prevent further outages, Hubbard said that, right now, the company was focused on alerting its customers that they could trade by phone if the Web site wasn't working.
Users said they could also make trades by phone.

We are working furiously to be fully operational before the market closes today, but we guarantee we will be real-time and free for the market open on Monday. Please send condolences to email@example.com."
