Zzoomm is the most likely one of those results to mean something.
Openreach "planned" result is really not very good and the data comes from
https://www.openreach.com/fibre-broadband/where-when-building-ultrafast-full-fibre-broadband, so the windows we're talking about are huge.
I'm super happy whenever anyone finds a new provider building for them via bidb
The "Unknown" result was just an error in the checker (which has since been fixed) and is totally meaningless.
This is
very quick. I would say it's extremely unlikely it'll be so quick for you. For instance, I have had a CityFibre CBT outside for about a year now with no sign of being services any time soon.
You could ask Zzoomm if the equipment is theirs and maybe try to ask about timelines?
