Data processing — Annex III — subprocessors
The authoritative list — each Subprocessor, what it does, and what data it touches — is maintained on the compliance page and forms Annex III of this DPA and of the SCCs.
It is a link rather than a copy on purpose. A second list here would be a second thing to keep current, and the failure mode is not that it looks untidy — it is that a customer relies on whichever copy they happened to read. One list, in one place, updated before a new category is added.
