Very happy so far with Digi 10Gbps Fibre, at 15 Euros a month.
This is from a new line installed as the first "tenant" in my office building; I'll update if it changes as more customers come online in my area - I am an early adopter.
The installation was 20 Euros - but the more important work of placing a distribution panel (specific to the Digi connection) in the ground floor of the building was no additional cost, and was arranged within a week after the initial engineer visited to do a site appraisal...luckily the internal fibre in the building seems adequate for this level of bandwidth.
Being realistic, very few hosts are currently going to support this bandwidth from clients - but for 5 Euros more than 1 Gbps, why not...
Combined with the unlimited calls and unlimited 5G for the 3 mobile numbers I have, at 5 Euros per contract, the whole package is less than a simple 1Gbps line at Meo or Vodafone.
I'll probably keep the Uzo 1 Gbps line at home, which is also 15 Euros a month, just for redundancy; if the office line goes down, I try 5G from the same provider. If that goes down, I walk home, use my laptop from a different provider. If that also goes down, I take a break and walk my dog...
That sounds like an incredible bargain. If you have all the kit to run at 10Gbps, you can probably saturate connections to several big services simultaneously. I agree that keeping a physically separate line for redundancy is probably a good idea.
