These small altnets are only going to get bigger by people signing up with them, as has already been said if they go under you can always go back to an ISP that uses the Openreach supported infrastructure. I don't know much about Zzoomm other than the ISP news here and on ISPReview.
I understand what you are saying, and they are all started from somewhere, and they have to build up their customers.
I am with plusnet for at least another 14 months anyway, my contract comes to the end in 2022, Myself I am not sure if I would want to go full fibre, well I suppose it depends on price. i have a good deal with plusnet at the moment and if they offer a good deal that is a fair bit below ZZOOMM price then i will stay with plusnet.
Zzoomm is £29 a month for the 100Mb/s according to their website, I am paying £23 a month for 35Mb/s with plusnet, may not seem a lot of difference, but it is £6 a month, ok, it may not seem a lot, but paying another £6 a month for something that is never going to be used to its full potential is a waste. I do that now with Netflix, which is why I am thinking of getting rid of it.
But if plusnet don't do me a decent deal i may change, depending on how much of a hassle it will be.
That is if I am still here and still have a job, lots of things can happen in 12 months, as this year have shwon.
Not much about Zzoomm on ISP review, apart from snippets of news, including them coming here.
Which is something I do not understand, why here?
My mate whom I was chatting to last night seems to think they have been given a load of money to come here. For what he pays for his broadband, which is 30 odd quid then for money alone going for Zzoom would be better for him, also he has 3 people in the house.
We will see
