The Eurocontrol ones come from their EAD website.The AR will probably be getting all this via the paid B2B interface.
Yet Autorouter get the same NOTAMs as you list for NOAA… This would mean that Eurocontrol has two different NOTAM databases? Why would that be, maintaining two different databases for no good reason does not make sense… Extra cost.
FWIIW, the French SOFIA-Briefing, the Belgian Internet self-briefing and ForeFlight all have the same NOTAMs as NOAA. EAD seems quite alone in this.

The FIR for Aldernay looks as if its BREST yet it is not a French airport
The Channel Islands are part of the LFRR (Brest) FIR, see https://www.eurocontrol.int/sites/default/files/2023-04/eurocontrol-firuir-lower-airspace-ectl-2023.pdf [local copy]
On the NATS website, I have seen similar problems in the past when the airport is in an unusual FIR, but it seems to work now. Perhaps the EADS site has problems when this is the case.
