Prefect
The subprocessor list as we last read it, on Nov 11, 2026.
Dates are when we read the list (UTC), not when Prefect changed it. Between two readings we don't know what it said.
tall: list changed · medium: document changed · short: read, no change · x: check failed · dotted: change dates only. Tap a tick or use the date box.
We record change dates, not every check, before Oct 11, 2026.
We have published no changes to this vendor's list; our first reading was Sep 23, 2026.
