WebKit closed bug 324771 as resolved and fixed on Oct. 9, four days after an iOS 27.2 beta went out. The public thread does not say which list entries changed.
The bug, titled “Inclusion of adsrvr.org in IS_REQUEST_UNCONDITIONALLY_BLOCKABLE domain list,” was filed on Sept. 21 Pacific time by Ian Meyers. The report describes adsrvr.org as The Trade Desk’s core ad request and delivery domain, and says Safari 27 added it to a set of unconditionally blocked domains. We covered the nine-entry list in Safari 27 Blocks Ad and Identity Domains, per a WebKit Bug Report, when the bug was still open.
The thread moved in short steps. On Oct. 5, WebKit’s John Wilander wrote: “A new iOS 27.2 beta went out today. Please test with it.” Meyers replied that he could see changes in build 24B5099f. On Oct. 9, Wilander wrote “Confirmed resolved.” The bug now shows status RESOLVED FIXED, priority P1 and severity Major.
Why it matters
The record answers one question: the reporter’s request was handled in a beta build, and WebKit confirmed it. It does not answer three others. The thread names no changed entry, gives no date for iOS 27.2 reaching the public release channel, and says nothing about the other eight domains in the report’s list. A status field is not a policy statement.
The original insight
This is our reading. The cycle from report to confirmation took 18 days, and nearly all of the public text came from two people. A vendor with a domain on the list cannot assume a fix for one entry covers theirs. The practical step is to test your own ad, sync and measurement requests on the 27.2 beta and keep the results, because that is the only evidence the thread currently invites.
