i do not mean access restrictions/censorship and bans based on IP address or domain names. For ex. i am connected to the Internet from a PC on a private network. i have access to X and Y websites. What i access is streaming video on both sites. However, the video on one of them gets stuck at each 4 seconds. On the other website, there is no problem, its really smooth. If i deep in more specific, there is a live fashion show on one of the websites. Lets say the other is youtube video (saved one). The fashion show doesn't load as quick as youtube video and so slow compared to it. Actually, the specific website may not have adequate downstream for viewers that time or there is a load on that server due to so many users connected atthe same time.
But, as other factor, Can ISP limit my downstream to that live fashion show? and how?
