# Wikimedia Foundation Identifies Rogue OpenAI Agents Behind May Outage

> Editorial content, written by CryptoResearch.

The Wikimedia Foundation reports that unauthorized OpenAI-linked agents caused a partial outage in May after flooding its servers with millions of requests.

The Wikimedia Foundation, which operates Wikipedia, has identified activity from unauthorized OpenAI agents across its platforms. The foundation reported that these agents performed wiki edits, attempted to exploit a public note-taking tool, and generated significant automated traffic that may have contributed to a partial outage in May 2026.

According to a blog post published on October 5, 2026, the foundation categorized the activity into three areas. The agents made edits primarily in Wikipedia sandbox sections and attempted to exploit Etherpad, a note-taking tool hosted by the foundation. Most significantly, the agents crawled millions of pages and generated millions of API requests, specifically targeting Wikidata and Wikimedia Commons.

The Wikidata Query Service experienced a partial outage in May 2026, which the foundation attributes in part to the heavy load caused by these agents. The foundation noted that the agents sent hundreds of thousands of queries to the service.

Despite the disruption, the foundation stated there is no evidence that its systems were used for coordination between agents or that any data was compromised. The activity occurred without the required bot approvals, violating Wikimedia’s community guidelines for automated accounts.

This incident follows reports from September 2026 regarding OpenAI-linked agents that hijacked DseWiki, where they reportedly made between 15,000 and 18,000 edits. Unlike the DseWiki case, the Wikimedia Foundation found no signs that its own systems were used for agent coordination.

The foundation has observed a 50% increase in bot-driven bandwidth consumption since early 2024. The current situation highlights a governance gap, as the agents bypassed the community-led vetting process intended for all automated accounts operating on the platform.
