How To Go From Number 50,000 to Number 20,000 on Technorati in 24 Hours
When I got into the office this morning I had the usual bunch of administrative tasks facing me. It was still early, so the phones weren’t yet ringing off the hook. Rather than face up to my routine duties, I decided to take advantage of my limited quiet time to do a little web research on a topic that has been nagging at me for the last couple of days [subject for another post].
Since Technorati seems to be issuing more search results, these days — and less of their infamously lame excuse —
Sorry
We couldn't complete your search because we're experiencing a high volume of requests right now. Please try again in a minute or two. We're working hard to make our search results better. Thanks for your patience.
— I’ve actually started to use Technorati Search again, from time to time.
I launch Technorati Search from my Profile Page bookmark, which I did this morning. Then I happened to notice the sudden dramatic change in Technorati’s ranking of my Sacred Cow Dung blog.
What happened?
Did I get Slashdoted (or is it “Slashdotted”?) last night?
I checked Sitemeter — Nope, Nothing unusual — Just my usual piddling traffic. No unusual (at least for me) recent posts. Server logs normal.
So I am clueless (as usual) as to what happened between yesterday and today to make my ranking soar. Technorati has apparently found that Sacred Cow Dung have twice as many links and site linking to it than it did yesterday (doubtful).
I’m just glad I collected my blog data (for my upcoming post “The Sacred Cow Dung 500 Analysis of the ACTUAL State of the Blogosphere” — Stay Tuned …) LAST week — before Technorati started tinkering (again?) with their “Authority” Algorithms.
The Technorati Effect
So, not only can you be “/.ed” with the “Slashdot Effect” but now you can be “Technorati-ed” by the “Technorati Effect”.
More on the “Slashdot Effect”, “Slashdotting”, and “Slashdotted”
Slashdot effect - Wikipedia, the free encyclopedia
Slashdot consists of brief submitted articles and a self-moderated discussion on each story. In response to the stories, large masses of readers simultaneously rush to view referenced sites. The ensuing flood of page requests, known as a slashdotting, often exceeds the ability of the site to respond in a timely manner, rendering the site slashdotted and, for many visitors, unavailable for a time, occasionally exceeding the site's bandwidth limitations or causing servers to slow down. A recent comment in a Slashdot story summarizes the effect nicely: "Slashdot is world famous. A roving random distributed denial of service attack before which web, network and systems administrators alike quake and have terrible nightmares about."
"Slashdotted" is sometimes abbreviated as "/.ed" in postings on the Slashdot site.

The Slashdot Effect, An Analysis of Three Internet Publications
[This is the most authorative overview of the “Slashdot Effect” that I’ve found. Cites three studies and includes several interesting graphs well-worth looking at.]
Apache httpd log files have been analyzed to show the Slashdot Effect. This effect is known as the spontaneous high hit rate upon a web server due to an announcement on a high volume news web site. Three papers were published on the Internet and announced on the high volume news web sites of slashdot.org, linuxtoday.org, and freshmeat.net. The hit rate plots as a function of time are correlated with the announcement times on these web sites. These correlations clearly demonstrate the magnitude and significance of the Slashdot Effect.
What a Slashdotting Looks Like | Threadwatch.org

Observation 1: Slashdotting hits instantly at peak - no build up, so there's no time for taking precautions
Observation 2: A good hosts is a good thing to have.
