subject [outages] Visualizing and confirming network anomalies - Newsight


[Apologies to those on NANOG who already saw this. Given the recent
discussion on this mailing list, it seemed appropriate to cross-post
it here.]

Hi folks,

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
network anomalies.

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:

Cheers,
Dave (on behalf of the Aqualab research group)

BitTorrentを利用したネットワークの問題を可視化するツールのリリースのお知らせ。
米国ではBitTorrentのユーザが多いのでそういうのもありか。
日本でもWinnyの開発者を逮捕/告訴なんかしてないでこういうプロジェクトに積極的に
取り込んでいけばいいのに、と思いますね。
