Websites associated with Rose City Antifa and the militant abortion-rights group Jane's Revenge have ceased operation in the days following the U.S. State Department's designation of their Italy-based technology provider, the A/I Collective, as a Specially Designated Global Terrorist.

The State Department stated that the A/I Collective provided essential digital infrastructure for violent far-left networks. "Today’s news demonstrates the extent to which the A/I Collective was the digital infrastructure of the global Antifa terror network," an official told Fox News Digital.

Following the designation, numerous servers and websites used by far-left extremists for planning violent attacks, targeting law enforcement, and concealing criminal activity have been taken offline, according to the State Department.

Among the affected sites is Rose City Counter-Info, a Portland-based website that the State Department claims Rose City Antifa utilized to publish personal information on Immigration and Customs Enforcement personnel and to coordinate violent actions against federal agents. Records indicate the site was used to distribute a flyer encouraging the use of laser pointers against Customs and Border Protection helicopters, an act for which one individual later pleaded guilty to aiming a laser at a CBP helicopter, forcing it to abort a mission.

Jane's Revenge also reportedly used A/I's services to publish claims of responsibility for attacks on pregnancy centers and to incite similar violence. The group has claimed responsibility for incidents such as the May 2022 firebombing of a crisis pregnancy center in Madison, Wisconsin.

The NoBlogs platform, which hosts thousands of websites and is supported by A/I, experienced intermittent unavailabilty, with some pages accessible while others returned errors.

The State Department has not specified whether U.S. agencies directly disabled A/I's infrastructure or if the outages were a result of actions taken by the collective, its vendors, or its users after the designation.

The sanctions imposed block U.S. persons and financial institutions from conducting business with the A/I Collective and freeze any assets it holds within U.S. jurisdiction. The department asserts that A/I provided encrypted communication services, web hosting, secure video tools, and anonymity services to violent left-wing groups in both the United States and Europe. Furthermore, the department alleged that a media organization using A/I services disseminated material from designated terrorist groups including Hamas, Iran's Islamic Revolutionary Guard Corps, and Hezbollah.

The A/I Collective has denied these allegations, describing itself in a statement as a small, volunteer-run technology collective from Italy that offers tools for "digital self-defense." The group stated, "We will not back down. Antifascism and anticapitalism are not terrorism. Protesting is not terrorism."

The State Department official characterized the designation as a "devastating blow to the transnational far-left networks that have plagued America and our allies for years."
