Bad ISPs

From VuzeWiki

The following is a list of Internet service providers (ISPs) that are known to cause trouble for BitTorrent clients or other P2P clients and the reason why. If you are using one of the following ISPs, please consider finding a new, better one. If your ISP is not on the list and you have reason to believe they are shaping traffic, come to the IRC channel and tell the OPs so that they can add it to the list. However, before you do that, please ensure that you have read about good settings and NAT problems.

One of the biggest problems are providers that perform traffic shaping on P2P protocols, see Avoid traffic shaping for advice on how to counter that. You'll need that if your ISP is listed with an encryption level greater than 0 or a question mark.

[edit] Notes

• Note 1: This information is hard to verify and thus only tentative
• Note 2: Enabling Tools -> Options -> Transfer -> Use lazy bitfield will probably help, try encryption otherwise
• Note 3: Download .torrents in .zip files, via HTTPS or use magnet links instead
• Note 4: ResNets, large Local Area Networks or Metropolitan Area Networks serving the personal computers of students in their residence halls or dormitory buildings on various university campuses, have no common governing body and hence have different policies on file sharing. The listed problems are those that are most frequently reported by Azureus users from different ResNet networks.
• Note 5: Appears to be blocking default port range; be sure to select a port in the 50,000s.
• Note 6: Appears to be blocking the bittorrent user agent for getting the .torrent file. change that via your client or use a localhost proxy.
