The Slashdot effect, also known as slashdotting or the hug of death, occurs when a popular website 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, servers 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.
