Behind Elon Musk’s X outage: What really happened and why it matters

What caused the X outage?

On March 10, 2025, X’s services went down for many users, causing frustration and confusion across the platform. 

The outages were significant enough to make headlines and draw attention from the tech community and the media. Elon Musk, ever the outspoken owner, quickly attributed the disruptions to a “massive cyberattack.”

While the initial response was that the attack might have originated from a coordinated group or even a nation-state, Musk’s comments pointed to Ukrainian IP addresses as the suspected source. However, he later clarified that the evidence was not definitive.

Also, several cybersecurity experts emphasized that attributing the source of such attacks based solely on IP addresses is unreliable, as attackers often use compromised devices worldwide to mask their actual location. 

So, what was the cause of X’s disruption? 

It was a large-scale, distributed denial of service (DDoS) attack. Such attacks involve overwhelming a server with so much traffic that it cannot serve legitimate requests, effectively bringing down the platform. This attack is a common method for cybercriminals to take down websites and was the primary factor behind X’s downtime. The technical side: How the DDoS attack impacted X

DDoS attacks are no small feat. These attacks flood the target’s servers with excessive traffic, rendering them unable to function correctly. 

It’s a strategy designed to exhaust a system’s resources and make it impossible for genuine users to access the service. Experts pointed out that the attack on X was massive and well-coordinated, taking down parts of the platform for hours.

Here’s a timeline of the events on March 10:

• Early morning (Eastern Time): Users began reporting issues accessing X, with over 21,000 reports in the US and 10,800 in the UK. 
• 9:30 am ET: A second wave of outages occurred, with about 40,000 users reporting disruptions. This outage persisted into the afternoon.
• Throughout the day: Users continued to experience intermittent access issues, with reports peaking during critical periods such as the start of National Football League free agency.
• Evening: By 6:24 pm ET, the number of reported issues decreased significantly to 403 in the US and 200 in the UK, indicating that the platform was stabilizing.

Security experts noted that some of X’s origin servers had not been adequately protected behind Cloudflare’s DDoS defense systems. This created a vulnerability that cyber attackers could exploit, contributing to the success of the attack.

Did any individual or group claim responsibility?

Yes, in the aftermath of the attack, a pro-Palestinian hacker group known as Dark Storm Team claimed responsibility. This group has been active since late 2023 and is known for targeting organizations and governments perceived to support Israel. Their tactics often involve DDoS attacks to disrupt services and draw attention to their political motives. 

While X took quick action to shore up these weaknesses, this incident served as a reminder that even the most prominent platforms are not immune to cyber threats if their security infrastructure isn’t up to the task.

Did you know? Cloudflare is renowned for its robust DDoS protection, having previously defended against some of the largest recorded attacks, including a 5.6 terabit per second assault in October 2024.

From fail whale to Musk’s era: Major X outages in history

Over the years, the platform has faced several high-profile outages caused by cyberattacks, internal errors and technical limitations.

In its early days, X (then Twitter) was notorious for frequent crashes, often displaying the now-iconic “fail whale” image to users. These outages were primarily due to the platform’s struggle to handle surges in traffic, particularly during major global events like elections, award shows and sports finals.

“Fail Whale” was Twitter’s old error message, showing a cartoon whale being lifted by birds. It appeared when Twitter was overloaded or crashed. It became a symbol of Twitter’s frequent outages, especially in its early days.

Notable incidents from Fail Whale to Musk’s X era include:

• 2016 Dyn DDoS attack: One of the most severe outages in X’s history occurred during the Dyn cyberattack in October 2016. This massive DDoS attack targeted a key internet infrastructure provider, taking down major websites, including X, Reddit and Spotify. The incident underscored the risks of centralized internet infrastructure.
• 2020 API failures: In October 2020, a widespread outage due to internal system changes led to API failures. While not a cyberattack, the event demonstrated how a misconfiguration could bring down the platform for hours.
• 2022 takeover disruptions: Following Elon Musk’s acquisition in late 2022, several outages occurred due to mass layoffs affecting critical engineering teams. Reduced staffing raised concerns about the platform’s ability to maintain reliability.
• 2023 rate limit issues: In July 2023, X imposed strict rate limits on users due to excessive data scraping. This decision led to widespread service disruptions, with many users unable to load tweets.

Did you know? The US Treasury is being sued for allegedly giving Elon Musk’s Department of Government Efficiency (DOGE) access to millions of Americans’ sensitive financial and personal data. The lawsuit, filed by the AFL-CIO, claims this access violates federal laws and raises significant privacy concerns. Lawmakers, including Senator Elizabeth Warren, have warned that Musk’s involvement could lead to unprecedented data misuse.

The growing importance of social media security

The X outage highlights the growing concern about social media security in today’s digital world. Platforms like X, Meta and Instagram have become crucial communication channels for individuals, businesses, governments and activists. Even X has become a hub for the crypto community, serving as a central platform for discussions, updates, and networking within the industry. However, these platforms are increasingly under threat from cyberattacks, misinformation campaigns and data breaches.

Here are some key areas where social media security is essential:

• Protecting user data: With millions of users actively posting, messaging and storing sensitive data, social media platforms are prime targets for hackers. Personal information, including emails, phone numbers and even financial data, can be compromised if security measures are weak.
• Enhancing user authentication: Stronger authentication methods, such as multifactor authentication (MFA), biometric logins and encrypted messaging, can reduce the risk of unauthorized access. Users should be encouraged to enable MFA to add an extra layer of security to their accounts.
• Fighting disinformation and fake accounts: Cyberattacks aren’t always about taking down a platform; sometimes, they aim to manipulate public perception. Fake accounts, bots and misinformation campaigns can create chaos, influence elections and spread propaganda. Social media companies must use advanced AI tools to proactively detect and remove such threats.
• Preventing DDoS and cyberattacks: As seen in the case of X, DDoS attacks can cripple a platform. While companies invest heavily in cybersecurity, hackers continue to evolve their tactics. This calls for constant vigilance and AI-driven security systems to detect and mitigate threats in real-time.
• Regular security audits and updates: Cybersecurity is an ongoing process. Social media companies must conduct regular security audits to identify and patch vulnerabilities before attackers can exploit them. Keeping systems updated ensures that the latest security measures are in place.

Finally, as you continue to integrate social media into various aspects of your lives, prioritizing security will ensure that these platforms remain trusted and reliable channels for communication and engagement.
