AI scraper bots overwhelm Gentoo's Bugzilla, forcing it offline

Gentoo has taken its Bugzilla bug tracker offline after a flood of AI scraper traffic overwhelmed the service. The announcement, posted by a Gentoo developer, points to automated bots — the kind used to harvest training data and feed AI crawlers — hitting the tracker hard enough to degrade it for everyone else.

The incident fits a wider pattern that has hit open-source infrastructure over the past year. Public-facing resources like bug trackers, wikis, Git forges, and mailing-list archives are cheap for aggressive crawlers to hammer but expensive for volunteer-run projects to serve, especially when bots ignore robots.txt, rotate IP addresses, and crawl every dynamically generated page. The result is effectively a denial of service, even when that isn’t the crawler operator’s intent.

The significance is less about one bug tracker going dark and more about the mounting cost that unrestricted AI data collection is imposing on the open-source commons. Projects are increasingly being pushed toward defensive measures — rate limiting, login walls, proof-of-work challenges, or pulling resources entirely — which raises friction for the legitimate human contributors these systems were built to serve.
