Cloudflare Outage May Have Cost an Average CFD Broker $1.6 Billion in Trading Volume

The three-hour Cloudflare outage yesterday (Tuesday) directly affected many forex and contracts for difference (CFD) brokers, with many websites showing the classic “Internal server error.” A pause in trading means a loss of revenue for these brokers.

Although none of the brokers publicly discussed their losses, FinanceMagnates.com estimates that the outage may have cost them an average of $1.58 billion in trading volume, which can be co-related as almost 1 per cent of their monthly trading revenue.

Cloudflair Protection Is a Must for Brokers

Monaxa, Skilling, Xtrade and FXPro are only a few names with confirmed impact during the Cloudflare outage.

Websites, including those of brokers, use Cloudflare not only as a CDN provider but also to protect their servers from cyberattacks. It has become a non-optional tool for websites that lack a large security team to protect their platforms. However, this heavy dependence also shows the vulnerability, which came out during the mass outage.

Reports indicate that the disruptions increased between 12 noon (GMT) and 6 pm, with a peak between 2 pm and 4 pm.

According to market data collated by Finance Magnates Intelligence, 27 per cent of daily trading volumes occur during those specific extended hours, while brokers handle roughly 20 per cent of that volume during the peak three hours when the outage occurred.

How Did We Calculate?

Excluding the top 10 CFD brokers by volume, none of which reported an outage, as they might not be using Cloudflare, the rest have a maximum monthly volume of $416 billion in Q3 2025, while the minimum is $40 billion, resulting in an average monthly figure of $174 billion. The estimated daily volume was $7.91 billion, taking into account the 22 trading days in the month.

Based on those estimated numbers, an average broker could have lost $1.58 billion in trading volume in those three hours. The smallest could have lost $364 million in trading volume, while the biggest ones could have seen this figure rise above $3 billion.

This average figure equals a loss of 0.91 per cent of brokers’ monthly trading volume, which can be rounded to 1 per cent and directly linked to 1 per cent in monthly revenue from trading. It is worth noting that the estimated losses may be partial, as traders typically return to settle their positions after such outages.
