Oversubscribe, of course. Overrun with persistent congestion, no. 1. Yes. 2. Any. 3. No, not really. 4.

Cogent is not a residential ISP. They are a business to business provider. As such, it should be possible to assume that their customers reasonably understand what they are buying and if they do not, the rules of caveat emptor should apply. Cogent’s failure to upgrade their peering (and their generally poor attitude towards peering overall) are one issue. The bigger issue in this discussion is their lack of transparency in secretly prioritizing traffic in order to further an agenda. IMHO, such conduct is unethical at best.
