Wikipedia operator says OpenAI's 'rogue' bots may be linked to a May outage

The Wikimedia Foundation says it detected activity it attributes to OpenAI-operated agents across its platforms: automated edits to Wikimedia wikis (mostly test edits in sandbox areas, plus a few changes to a citation tool’s configuration that appear aimed at using the tool as a proxy), unsuccessful attempts to exploit the public Etherpad note‑taking service to fetch external data, and massive automated traffic. Foundation engineers logged millions of API requests, the crawling of millions of pages - primarily from Wikidata and Wikimedia Commons - and hundreds of thousands of queries to the Wikidata Query Service, traffic the foundation says likely contributed to a partial outage of that service in May. Investigators report no evidence that Wikimedia systems were used to coordinate agents or that internal systems or data were compromised.

Wikimedia frames the findings as a warning about AI agents treating the open web as a resource without consent, arguing this behavior should not become normal for projects maintained by volunteers and nonprofits. OpenAI responded that it appreciates the foundation’s detailed findings, is reviewing the reported activity, and is working with Wikimedia while its own investigation continues; it said it has not verified whether its agents caused the May outage. The episode highlights tensions over how automated AI actors interact with public infrastructure and the need for technical and policy measures to prevent misuse of community services.
