Cool visualisation of a Distributed Denial of Service (DDoS) attack

You may have heard of the term “Denial of Service Attack”. It’s basically when a website is prevented from working by another source (or sources) repeatedly requesting resources from the host server.

Think of it like getting yourself and thousands of your closest friends clicking “refresh” on the same website at the same time over and over and over again. More often than not, the web server can’t cope and anyone legitimate who is trying to access the same site will see an “over capacity” message (see:¬†fail whale on Twitter) or worse still will sit there waiting for the site to load and eventually give up.

Someone recently produced a video of a DDoS attack on one of their websites. The video uses Google’s logstalgia visualisation tool that¬†replays access logs in a “pong-like battle between the web server and an never ending torrent of requests”.

It’s pretty cool, albeit in a geeky way, but thought you might like to see it:
