Is myspace using memcache?

I'm lead web developer for the largest e-commerce shop in northern
Europe, Komplett, the largest shop is www.komplett.no
<http://www.komplett.no/> , but we have shops in most northern European
languages, for example www.komplett.co.uk <http://www.komplett.co.uk/>
. Our core platform is based on MS tech and we use memcached to cache
all our product info (as XML). Two Win32 memcached 1.2.1 instances with
1GB cache each, with about 700.000 items in each cache at any given
time. Yesterday we served about 1.2 million pages.
We've had no problems whatsoever with the Win32 1.2.1 memcached version
since we migrated to it a couple of months ago. At first we ran
memcached on a Debian box, then we tried a VMWare appliance (Hermes),
but Hermes crashed every 3-4 days with out of memory errors. The Debian
box worked great, but Operations wanted us over on a pure MS platform,
so we had to move it.
So I want to extend a big "thank you!" to everyone involved in the
memcached project and especially those porting it to Win32 and making
binaries available, you have a great project here and you run it well!
(Looking forward to a Win32 port of 1.2.2... :-) )
Let me know if you want to know anything more specific about our setup
and I'll try to answer.

Yup, thanks mike, I couldn't agree more. Facebook is just awesome. I
only really asked about myspace because I know they are a microsoft shop
and therefore another website that is MS technology based using memcache
would help just as much. Thinking on it now I should have posed the
question: What MS Tech based companies are using memcache?
I love memcached myself, it is so easy and powerful. And yes I
appreciate Steve's posts about Facebook and how they are using
memcached, the information is very helpful.
I've got the win32 binaries working with the .NET client tools from the
danga website. It all looks to work just as good as the *nix versions,
does anyone have any experiences to the contrary?

myspace should not be used as a technical model for anything.
imho, with as much capital as they should be able to use, the
inconsistent and completely buggy interface is uncalled for -
especially going on for this many years.
facebook would be a much better model. not only is their site clean,
consistent, (and uses memcached i might add) but they expose APIs now
and seem to generally know their technical stuff. exposing APIs in my
mind is the next step when you have successfully been able to please
users with your frontend interface. (some people may disagree, saying
APIs are nice because other people can make their own interfaces and
you don't have to change yours)
to me myspace was built not to scale properly and ever since has been
struggling to do anything to support the load. i mean come on - it
started with coldfusion. did they really expect to be one of the
busiest sites on the net starting with that? :)
i really don't think they've put in enough funding or the proper
resources from what it seems like, unless they have a secret
completely rewritten version in the works.
not only does facebook use memcached, but steve is one of the most
active posters it seems and him/the team he works with has made
numerous improvements and i'm quite sure runs one of the largest (if
not the largest) memcached clusters anyone has ever claimed that i
