The problem is not the Mageia internal or reference mirror.
The problem is do we get enough big, fast and reliable mirrors that:
1. can be a Tier1
2. want to host that much data

This also affects how many downstream mirrors that want to help,
as they all ask: "do we want to host another ~1TB or so..."

And without enough good Tier1 mirrors, the few (one?) existing ones will 
be overloaded, and mirroring will take a long time, meaning several 
mirrors will have outdated / not fully synced mirrors -> Mageia gets 
complaints about unreliable mirrors...

So it's sure something to think about...
