We are going to need a bigger boat.
That clip is the exact reaction I had when I walked into my office last Monday morning. Beginning last week, we got absolutely crushed/overwhelmed with traffic. A site that we developed and hosted was suddenly 'discovered' by the media (fox, associated press, USA Today, front page of DIGG, etc). Check out the sheer number of stories on it on google news here It continues today, like right now....currently our site is featured on the front page of CNN. Its a site that shows HIV disease prevalence across the country by county (and in some cases zip code) maphiv.org. I will warn you that registration (its a quickie) is required if you are interested.
Its an ArcGIS Server javascript api based site running on 9.3.1 using msd's & mxd based services with multi layer caches. We plan an extensive series of posts when things calm down a bit that will focus on the many lessons that we learned from this overwhelming amount of traffic.
QUICK UPDATE 12 noon edt: Our ArcGIS server is taking close to 20 requests per second and still holding strong.

We maintain a couple of sites using 9.3 with dynamic layers and cached layers (see http://www.longislandindexmaps.org and http://www.urbanresearchmaps.org/oasis/map.aspx/), and we're planning to move soon to 9.3.1 for the MSDs, etc.
Interesting that you say you use multi layer caches. ESRI's help files say that multi layer caches don't provide
any performance benefit in a web environment, only when the client is Desktop.
I know they say there is no performance difference. Not sure why they say that... Check out this post on the subject: http://www.roktech.net/devblog/index.cfm/2009/2/12...
The MSD's are worth the upgrade...
Not sure why those hrefs aren't getting picked up correctly...Either, I checked those out, and you did a great job. They look fantastic.
redirect to the actual page. But thanks for the kudos.
