Apple’s iOS 27 reportedly blocks ad-tech vendors, with wider restrictions possible
Apple’s iOS 27 reportedly began blocking major data, identity and ad-tech vendors, including The Trade Desk’s adsrvr.org domain. A new iOS 27.2 beta removes that domain from the blocklist, but a broader potential list covering hundreds of vendors could still disrupt audience activation, identity, targeting and measurement. Apple has not confirmed the wider plans.
Why it matters: Marketers and agencies may need to reassess audience activation, attribution, identity and media-buying dependencies on affected vendors, while preparing for further WebKit restrictions. The development is both broad and potentially durable, although evidence is based on one specialist report and Apple has not confirmed the wider blocklist plans.
