World Chess

World Chess, also known as worldchess.com, is an organization headquartered in the United States of America. It operates a website that provides online services related to chess, most notably the live broadcast of the World Chess Championship Candidates Tournament. The organization’s online platform is accessible via the domain worldchess.com. Its primary public-facing activity involves delivering exclusive live coverage of chess events to viewers worldwide.

In March 2016, the World Chess Championship website experienced a denial-of-service attack during the Candidates Tournament. This attack disrupted the exclusive live broadcast of tournament games and moves, preventing fans from following the matches in real time. The incident occurred amid existing criticism from the chess community regarding the organizers' decision to restrict access to the platform and select partners. The denial-of-service attack exacerbated frustration among viewers who were unable to access the live coverage. The event was reported by security commentator Graham Cluley on his blog, highlighting concerns about the commercial viability of the championship and sponsor dissatisfaction. While the organization's primary focus appears to be the delivery of chess event broadcasts, further details about its size, ownership structure, or additional services are not provided in the available sources.
