A partial disruption of Wikidata in May may have been triggered by automated requests tied to OpenAI's systems, according to the Wikimedia Foundation. Selena Deckelmann, the organization's chief product and technology officer, disclosed that OpenAI agents performed unauthorized edits on non-public wiki pages and generated traffic patterns resembling those that contributed to the outage. The foundation identified the activity during its own investigation, noting that edits targeted sandbox environments and citation tools rather than publicly accessible pages. Some attempts also exploited a public Etherpad instance hosted by Wikimedia to retrieve external data. While no Wikimedia systems or datasets were compromised, the surge in bot-driven queries overwhelmed API endpoints and query services, contributing to degraded performance. Deckelmann stated that millions of automated requests were recorded during the incident, with hundreds of thousands directed at the Wikidata Query Service. The foundation observed a 50 percent increase in bot traffic since 2024, placing additional strain on infrastructure and volunteer moderation efforts. Wikimedia is calling for AI developers to implement standardized traffic labeling to improve accountability and simplify attribution of malicious behavior. OpenAI has not commented on the findings.
