The term comes from the image of a whale being lifted by birds that accompanied the error message.

Key Takeaways

  1. Fail Whale is an error message illustration used by Twitter to signify when the platform is overloaded or experiencing downtime.
  2. Designed by Yiying Lu, the iconic image features a whale being lifted by a flock of birds, which symbolizes the weight of the platform’s traffic.
  3. Though it became a popular symbol, Twitter gradually phased out the Fail Whale as they made improvements in infrastructure and reduced instances of downtime.


The term “Fail Whale” is important because it represents a critical moment in the history of social media, particularly Twitter.

The Fail Whale is an error message, featuring an image of a whale being lifted by birds, which appeared on Twitter when the platform experienced overcapacity or technical issues.

During Twitter’s early years (circa 2007 to 2013), as the platform experienced rapid growth, the Fail Whale became a notable symbol, often trending and gaining significant public attention.

It highlighted the need for social media platforms to ensure stable and robust infrastructure capable of handling immense levels of traffic.

Ultimately, the Fail Whale demonstrated the challenges associated with scaling emerging technologies and the importance of addressing such issues to maintain a positive user experience.


The Fail Whale serves as a user-friendly representation of error messages for applications, particularly denoting issues in service capacity and overloaded servers. Oftentimes, websites and online platforms experience surges in traffic, which can exceed the capabilities of the servers hosting them.

In such cases, developers opt for a visual cue to inform users of these temporary downtimes or technical hiccups. The Fail Whale serves the purpose of engaging users’ attention with a lighthearted image during unfavorable situations, thereby softening the blow of potential frustration.

Its intended use is to communicate these occurrences in a manner that fosters understanding and patience among users, while the technical team works behind the scenes to resolve the issue. A notable example of the Fail Whale is the icon that was widely used by Twitter during its early years, when the platform experienced frequent service outages and periods of instability.

When users attempted to access the site but failed due to server limitations or high volumes of traffic, they were presented with an illustration of a whale being lifted by several birds, with the accompanying text “Twitter is over capacity.” The Fail Whale not only became emblematic of Twitter’s growing pains but also garnered a cult following in the tech community as a symbol of server overloads. The use of such a relatable image was effective in creating empathy and understanding among users, allowing them to remain receptive to the application despite encountering issues and ultimately resulted in better user experiences.

Examples of Fail Whale

The “Fail Whale” is an iconic error message that was displayed when Twitter’s backend servers were struggling to cope with the number of incoming requests during its early years. It was an image of a whale being lifted by several birds, indicating that something went wrong on the site. Here are three real-world examples of when the Fail Whale appeared:

2008 US Presidential Election: On election night, November 4, 2008, the high volume of people tweeting about the election results and discussing the event caused Twitter’s servers to become overwhelmed, resulting in the appearance of the Fail Whale.

2010 World Cup: During the summer of 2010, soccer fans from around the world took to Twitter to express their excitement and support for their teams. The volume of tweets was so high that the Fail Whale made several appearances throughout the event – particularly during the most exciting matches.

Michael Jackson’s Death: On June 25, 2009, the sudden and shocking death of pop icon Michael Jackson led to a massive surge in tweets related to his passing. The high traffic of users discussing this news caused the Fail Whale to appear once again as Twitter’s servers struggled to handle the demand.In following years, Twitter has improved its infrastructure and scalability to handle large volumes of users, but the Fail Whale remains the symbol of server overload in the world of social media.
