I chose IDNet over a year ago because of their promise on not over provisioning a circuit. Whilst they may not be as cheap as some of the competition this was a huge selling point and I ALWAYS get my advertised speed I first started out on 160/30 and I always got my speed, then an appealing offer for 1000/115 came up for £11 more a month and I jumped (I've yet to drop down below 900/100) and been happy I switched since.
Other ISP's have since popped up in my area offering similar services for cheaper but I just can't bring myself to move away from such rock solid connectivity.
When I was in presales stage I had a fair few questions and was always promptly responded to by the customer support team.
My internet has never gone down during the day and if it has overnight it's for a very small amount of time that is barely even noticeable.
I'm extremely happy and cannot state that enough, especially as I can use all my own hardware and very happy to see IPV4 and IPV6 bundled in at no additional cost (Again another selling point for me)
