Popular trading app Robinhood recently maxed out a major credit line in response to suffering multiple system-wide outages, Bloomberg reports.

The Menlo Park startup withdrew its entire $200 million credit facility with prominent banks JP Morgan Chase, Barclays, and Citibank during the week of February 24, the outlet’s sources said.

A spokesperson told reporters that Robinhood had already repaid the borrowed money, and noted the company has “additional larger credit lines” that it didn’t use at all last week.

However, the firm denied the loans were related to its system failures, telling Bloomberg: “Our capital position remains strong. We determined it was prudent to draw on our credit line during the week of Feb 24 in light of market volatility.”

Founded in 2013, the firm says it services more than 10 million active users, and boasted a $7.6 billion valuation in July 2019.

Robinhood down during most epic trading days in modern history

Hard Fork previously reported on Robinhood‘s downtime troubles, which locked users out of their accounts for the entire trading day last Monday — when the stock market gained $1.1 trillion in value, and the Dow enjoyed its highest point increase in a single day in history.

“Options” traders were especially affected. Robinhood automatically finalized contracts under certain conditions independently of users, who were unable to execute such decisions themselves.

The app would go down twice more: for three hours as markets opened the very next day, and again this Monday, which coincided with the S&P 500’s worst market performance in a single day since 2008, closing 7.6% down.

This means Robinhood users couldn’t trade during two of the most volatile trading days in decades.

Robinhood promised traders $15 off subscriptions to make up for the downtime, and said it would explore additional compensation on a case-by-case basis in the future.

Rivals aren’t kicking RH while it’s down… but regulators might

While the firm is yet to disclose exactly what caused Monday’s disruption, Robinhood blamed last week’s outages on an unprecedented number of sign-ups and spiking trade volumes, leading to infrastructure failures — specifically its Domain Name Service systems.

One might expect the firm’s rivals to skewer Robinhood for going dark over and over again. However, most seem sympathetic with the influential startup, with many claiming to be under similar technical stress.
