The Slashdot effect, a term coined in the early 2000s, refers to the temporary inaccessibility of a website due to a sudden influx of traffic following its mention on popular Internet^[1] platforms like Slashdot, Reddit, and Twitter. This surge often results in slower load times, overloaded servers, and potential downtime, posing a significant challenge to optimal web performance. The name derives from the tech news website Slashdot, notorious for triggering such traffic spikes due to its substantial influence on internet activity. Although less common today, the Slashdot effect emphasizes the critical need for website scalability and performance enhancement, particularly in today’s landscape of viral social media content. To mitigate the impact, strategies such as employing Content Delivery Networks, page mirroring, load balancing, and dynamic server scaling are recommended. As a subject of digital culture study, the Slashdot effect provides valuable insights into the technical consequences of sudden online popularity.

1. ↑ Internet. L'internet, réseau mondial de systèmes informatiques interconnectés, utilise des protocoles de communication normalisés, principalement TCP/IP, pour connecter des appareils à travers le monde. Le terme "Internet" trouve son origine dans le terme "internetted" de 1849 et a été adopté par le ministère américain de la guerre en 1945. L'origine de l'internet remonte aux années 1960, lorsque des informaticiens ont mis au point des systèmes de partage du temps, qui ont finalement abouti à la création d'ARPANET en 1969. L'internet fonctionne de manière autonome, sans aucun contrôle central, et l'Internet Corporation for Assigned Names and Numbers (ICANN) gère ses espaces de noms primaires. Il a révolutionné les méthodes de communication traditionnelles et a connu une croissance exponentielle, le nombre d'internautes augmentant de 20% à 50% chaque année.

Effet Slashdot (Wikipedia)

Les Effet Slashdotégalement connu sous le nom de slashdotting, occurs when a popular site web links to a smaller website, causing a massive increase in traffic. This overloads the smaller site, causing it to slow down or even temporarily become unavailable. Typically, less robust sites are unable to cope with the huge increase in traffic and become unavailable – common causes are lack of sufficient data bandwidth, serveurs that fail to cope with the high number of requests, and traffic quotas. Sites that are maintained on shared hosting services often fail when confronted with the Slashdot effect. This has the same effect as a denial-of-service attack, albeit accidentally. The name stems from the huge influx of web traffic which would result from the technology news site Slashdot linking to websites. The term flash crowd is a more generic term.

The original circumstances have changed, as flash crowds from Slashdot were reported in 2005 to be diminishing due to competition from similar sites, and the general adoption of elastically scalable cloud hosting platforms.
