How much content is being ip blocked?

I say this because I pay for content hosting solutions via mega.nz and other platforms, and the only way of now being able to get access to them is by the means of now having to pay for a vpn, or change my dns. This has become a recent issue, I have tried getting access on three different machines, different browsers all using my connection to no avail. I made contact with the providers who assured me that there is no server issues at their end, this was apparent when I gained access via vpn in france. So I can only assume that Virgin has added certain hosts to it websafe block list without informing anyone.

Repeatedly tried to phone for confirmation, from the tech services and was met with indifference and more pushy sales garbage than a street seller on a bad day in vegas. I know my way around, gateways, dns and ip management along with networks. So don't be afraid to jump in.. with sugestions
