Earlier quoted context omitted.
But customers are already paying for 'unlimited internet' -- or for some amount of data up to a cap. You're suggesting that we should double charge the providers that the customers want to access, as well?
Telekom already does this for a very long time, at least in Germany. see for example https://news.ycombinator.com/item?id=10645577
Also, does the ISP who wrote that linked article, Hetzner, still support net neutrality? I can't find anything else in English about it since the linked article from 2015 (archive [1], and new link [2]), but maybe that's because other content hasn't been translated.
> Hetzner Online stands for high-performance and high capacity Internet. In the last few years, our network infrastructure has expanded little by little in order to provide our customers with optimal performance. Currently, about two-thirds of our network traffic is directly exchanged with cost-neutral peerings of various partners. Among them are privat peerings with large network operators.
> For this reason, we have been increasingly concerned with DSL and cable providers who have no open peering policy themselves but are also not connected to other Tier-1 carriers with sufficient capacities. During the peak traffic period of 7 pm to 10 pm in particular, the concerned DSL and cable providers hit their capacity limits and thereby impede the fluent data stream between individual networks. This has lead to increasing complaints from the providers' customers because the customers cannot access their servers with the level of performance that they are used to having from Hetzner Online.
> These customers already paid for comprehensive and quick access to the Internet with their monthly DSL and cable fees. However, providers are no longer satisfied with just this source of profit. They now also want to collect revenue by charging large content providers fees for access to their network. For this reason, interfaces are being operated at their highest capacity -- to make paid access to the DSL and cable providers' networks attractive for content providers. The end consumer is then forced to pay double for unlimited access to the Internet. We at Hetzner Online do not support such policies and declare our support for full net neutrality.
