[비즈한국] On the morning of the 18th, a large-scale YouTube service outage occurred globally. Error reports flooded in simultaneously from across the US, Europe, Asia, and South Korea, with some users unable to access the app or website, or experiencing malfunctions with the home screen, subscription feeds, and Shorts features. Hundreds of thousands of reports were filed on outage tracking services, effectively creating a situation akin to a total global service blackout.
Google, a subsidiary of the parent company Alphabet, initiated recovery operations and restored normal service in about an hour, but the specific technical cause has not yet been officially disclosed. International media are citing the possibility of internal system errors or network infrastructure issues.
While the service interruption lasted just over an hour, the economic impact is significant. According to the 2025 performance data recently released by Alphabet, YouTube's annual revenue (including advertising and subscription services) is approximately $60 billion, or about 81 trillion won. Simply put, this breaks down to about $6.85 million in revenue per hour, or approximately 9.247 billion won. Given that this outage lasted for about an hour globally, it is highly likely that the direct advertising revenue loss alone reached the 9 billion won range.
Of course, this is merely a calculation based on an average. In reality, given that it was the morning of the final day of the Lunar New Year holiday, traffic was likely higher than usual. In the IT industry, as it was a peak time for travelers to watch mobile videos, the possibility that the actual scale of the loss exceeds the average cannot be ruled out.
A bigger problem than the platform's own loss is the chain reaction that spread throughout the YouTube ecosystem. Considering YouTube's revenue-sharing structure, it is possible that about 4 to 5 billion won in advertising revenue that should have gone to creators evaporated. Since it was a holiday morning when views typically surge, the perceived losses for individual creators and MCN (Multi-Channel Network) companies are likely to have been even greater.
Advertiser damage is also significant. With targeted ads and real-time streaming campaigns designed for exposure at specific times failing to broadcast normally, many brands lost touchpoints with potential customers. This can lead to more than just the loss of ad spend, potentially resulting in reduced promotional efficiency, data distortion, and a decline in brand credibility. If we further consider potential compensation for paid subscription users like YouTube Premium and YouTube TV due to their inability to access the service, the total damage including indirect costs is likely to exceed the simple decline in revenue.
This YouTube outage demonstrates that in the structure of global platform revenue and the nature of the advertising ecosystem, even a short service gap can have a significant economic impact. The actual scale of the loss may vary depending on the traffic levels and ad execution structure at the time, and more specific figures are expected to become clear through the company's future explanations and additional analysis.
Similar cases have repeated in the past. In 2021, Facebook, Instagram, and WhatsApp under Meta went down simultaneously for about six hours, causing major chaos for global advertisers and small business owners. In 2020, a Google Cloud outage temporarily paralyzed major services such as Gmail and YouTube. Industry experts point to the structural problem of recurring single points of failure in massive platforms and observe that an increasing number of advertisers and content companies are moving to diversify their reliance on specific platforms.
