Too Big to Fail? The Largest Outages in 2024 According to Downdetector | Ookla® (2025)

Our reliance on technology is so total that for many it feels like the world is ending when a popular site or service on the internet is inaccessible, and 2024 saw many outages that reminded us how much one such interruption can disrupt the daily lives of millions. We analyzed Downdetector® data from Q1-Q3 2024 to see where that pain of disconnection was felt most acutely. Read on to revisit the largest outages of 2024 at a global level and sorted by region.

Note that while some companies experienced more than one large outage during this time period, we’ve listed only the largest incident per company in each chart.

The world’s biggest outages this year

Users of social media sites, internet providers, and gaming sites and services suffered the most disruptions this year according to Downdetector data on the world’s biggest outages. Facebook had the largest outage on our list. On March 5, over 11.1 million people across the world reported issues with the popular social media site.

The second largest global outage may be the most memorable. While CrowdStrike is not a service most people think of, we saw nearly 5 million reports to services that rely on it (or rely on Microsoft which relies on Crowdstrike), including emergency services, airlines, and ride sharing apps when a routine software update went bad on July 19.

AT&T suffered the third largest outage in the world, according to Downdetector data, when an equipment configuration error caused customers across the entire United States to lose network access for over 12 hours.

Biggest outages in each region

Asia Pacific region hit by global outages

The March 5 Facebook outage also topped the list of outages in the Asia-Pacific region, instigating over 908k user reports to Downdetector and taking Instagram down with it as the second largest outage. The third largest outage happened on June 26 when over 168k Microsoft 365 users in the Asia-Pacific region reported service disruptions on the service. Japan was especially hard hit with over 139k user reports from that country alone.

People in the Asia-Pacific region were also affected by local outages, with over 76k users reporting issues with Japanese payment system PayPay in May, and 65k users in India reported issues with Jio during a September service disruption.

Europe struggles with social media sites

Social media sites were the main source of disconnection in Europe according to data from Downdetector. Over 3.4 million European users reported issues with Facebook during the March 5 outage, making that the largest outage in Europe during Q1-Q3 2024. WhatsApp users suffered the second largest outage in Europe with over 1.1 million people reporting issues during an outage in early April.

Two German companies also showed up on our list of largest outages in Europe with over 218k reports of issues with 1&1 and over 209k reports of issues with Deutsche Telekom when the two companies experienced service disruptions almost a week apart in late May.

Latin America feels pain from global social outages

Latin America’s top three outages mirrored those in Europe with social media sites causing the most pain for users according to data from Downdetector. The March 5 Facebook outage was felt profoundly with almost 850k user reports on Downdetector in Latin America for issues related to Facebook and over 260k related to Instagram. WhatsApp had the second largest outage in the region with almost 420k user reports during the two hours the service was down on April 3.

Bait, a Mexican Mobile Virtual Network Operator (MVNO) owned by Walmart, suffered an outage on April 2 where almost 99k users reported issues to Downdetector. And on September 24, over 74k users reported issues with Brazilian fintech bank Nubank.

Middle East and Africa experience mix of local and global outages

Outage patterns in the Middle East and Africa differed from those in other regions with users reporting about as many issues with local sites and services as global ones. The two largest outages, Microsoft 365 on March 14 and Facebook on March 5, were part of global events.

The third largest outage in the region was with South African telecommunications provider Telkom. Almost 55k users across Africa reported issues to Downdetector when Telkom experienced an outage on May 13. MTN, Vodacom, and du are other telecom providers that made our list of top outages in the Middle East and Africa during Q1-Q3 2024.

United States and Canada

As we saw with much of the rest of the world, Facebook topped the list of outages in the U.S. according to Downdetector with over 5.8 million users reporting issues with the service during its outage on March 5. The Crowdstrike and AT&T outages also hit the U.S. hard with almost 5 million and over 3.4 million user reports, respectively. Gaming sites and services and telecom providers filled out the rest of the list in the U.S.
