Denial of Service Attacks - explain?

Zascar · 2009-07-08 13:09:52

So I just saw that one of the large Irish hosts got hit by one of these. I have heard of them plenty before but really I do not understand exactly what they are. So can someone please explain? How to they happen, and why? How do you stop them? Are they always intentional and malicious?

Not always. Once had some malconfigured but legitmate robots going beserk on one large site I ran, to the extent that the logfiles grew at a ridiculous rate over a weekend until the disk got maxed out causing the OS to crawl. Though that was from a set of subdomains as opposed to a distributed botnet.
