Apple’s iOS 27 Appears to Block The Trade Desk Ads on Safari
Apple’s iOS 27 appears to have blocked adsrvr.org, The Trade Desk’s core ad-request and delivery domain, from Safari on updated Apple devices. The blocklist also includes several identity and tracking services. The Trade Desk has asked Apple’s WebKit team to investigate, but the scope and durability of the issue remain unresolved.
Why it matters: Advertisers and agencies using The Trade Desk may face Safari inventory loss, delivery and reach changes, measurement implications, and a need to review media plans and alternative buying or identity approaches. The development could also signal broader platform control over programmatic access, but its final scope and durability are not yet confirmed
