I had a heated conversation with a Hyperoptic rep a couple of years ago on another forum via pm's, which resulted in me deleting alot of post's, out of a thread about them because it ended up with me told by my now ex manager to remove them or I would get a written warning, I can only guess they were in discussions with VM at the time.
They claimed they were able to give each person in a MDU (multi dwelling unit) a 1Gb connection, that would give them 1Gb to other countries and when questioned about it, I got a fair bit of abuse about it and told to shut up as I didn't know what I was talking about.
When I mentioned who I to worked for at the time, they stopped responding to questions and instead just started to try and get me banned of the forum which didn't work and then they dropped of the forums and went quiet.
All I was interested in finding out was if it was a true 1Gb connection rather, than 1Gb throughout the UK and then if the speed dropped to less than 1Gb when leaving the UK, as it would have got me interested in there services but they wouldn't answer and after the abuse I got I decided I wouldn't think about signing up to them if they ever came to where I live.
Not many companies can offer a 1Gb connection to outside of the UK for the price that they charge, as that is basically classed as a Business Connection and they cost a fair bit more than £60 a month.
When I asked if they would also install just a single occupancy home, they said that they would but it would cost nearly £2k to install it as they prefer to do MDU's.
They may have changed since then but if people want to sign up to them, go ahead but make sure you are getting what they claim and not some poor attempt at a decent connection which, is limited to only giving you the quoted speed within the UK.
With BT, VM etc you get the speed you pay for within reason within the UK and when your data leaves the UK.
