Amid a widespread global IT outage, some investors were experiencing disruptions on Friday at financial services companies, including Charles Schwab , one of the country's largest brokerage firms.
The issues stem from a faulty software update from cybersecurity company CrowdStrike, which affected businesses worldwide, including airlines, banks and media outlets.
CrowdStrike CEO George Kurtz said the company is "actively working with customers impacted by a defect found in a single content update for Windows hosts."
A banner across Charles Schwab's website said "certain online functionality may be intermittently slow or unavailable," noting that phone services may be disrupted with "longer than usual hold time."
Charles Schwab did not immediately respond to CNBC's request for comment.
