We've just released a new tool that allows you to see network problems
from end-user machines, currently BitTorrent users. (Think of this as
putting P2P traffic to good use.) The interface that we've provided is
still very beta, but we'd appreciate any (constructive) feedback.
A little more detail: we've deployed software called NEWS (network
early warning system) that uses P2P users' natural traffic to detect
sudden, unexpected drops in network performance -- this allows our 25k
BitTorrent users to corroborate network problems with each other. Our
tool, called Newsight, lets you see summaries of their reported
You can browse a timeline of anomalies grouped by country, AS or
prefix. You can also confirm known network problems, helping to create
a public database of outages and their explanations.
You can play with Newsight here:
