Glasnost – Check whether your ISP is Manipulating P2P Traffic
Posted by: | Comments
Here is another good untility to Check whether your ISP traffic shaping, boosting or blocking your bit torrent traffic. This is a good solution for those to find out if the slow bit-torrent speed is due to the client misconfiguration or due to traffic shaping techniques by their ISPs.
Certain ISPs have been shown to rate limit or block BitTorrent traffic sent by their customers. While there are multiple reports of this on the web, only a few ISPs have admitted that they manipulate BitTorrent traffic. And, to date, it is hard for users without networking expertise to gain evidence about the behavior of their ISP.
This test suite creates a BitTorrent-like transfer between your machine and our server, and determines whether or not your ISP is limiting such traffic. This is a first step towards making traffic manipulation by ISPs more transparent to their customers.
Glasnost test focuses on the popular BitTorrent protocol as many ISPs are suspected to manipulate BitTorrent traffic. This type of traffic can be identified by the port it is sent on (e.g., TCP port 6881) or by BitTorrent content headers which occur in the packets.
Therefore, their online tool to detects whether your ISP is using one of the following techniques:
- Throttling all BitTorrent traffic.
- Throttling all traffic at well-known BitTorrent ports.
- Throttling BitTorrent traffic only at well-known BitTorrent ports.
Note that some ISPs do not throttle all BitTorrent traffic but only if this traffic exceeds a certain threshold. Thus, passing their tests does not necessary mean that there is no throttling occurring on your link.

Facebook Confirms Denial-of-Service Attack
Posted by: | Comments
Facebook has confirmed to Wired.com that — like Twitter — it was the victim of a denial-of-service attack Thursday morning.
The service has been working just fine for me, but I contacted the Facebook press office to ask whether the rumors of an attack were true.
“Earlier this morning, Facebook encountered network issues related to an apparent distributed denial-of-service attack, that resulted in degraded service for some users,” responded Facebook spokeswoman Kathleen Loughlin via e-mail.
“No user data was at risk and we have restored full access to the site for most users,” she added. ” We’re continuing to monitor the situation to ensure that users have the fast and reliable experience they’ve come to expect from Facebook.”
If Facebook was attacked by the same party or parties who drove Twitter offline today, as seems likely, it means two things: First, Facebook is more resilient to denial-of-service attacks than Twitter is; and second, someone — or something — really wants both Facebook and Twitter offline today.
