In which datacenter is Qaiku located? (Sigmatic mount) And what software / hardware is powering the whole lot?

Whois info indeed points to Sigmatic. Sigmatic says they're using Dell Poweredge servers. Server OS is Ubuntu, and site is running on LAMP + Midgard stack. HTTP headers give this away.

I've been following the development so I knew some of this, but above is from public sources. ;)

Sigmatic runs their own datacenter. I guess it's in Helsinki region.

@mandrl's info is solid:)

@mandri Checking the http headers, which can be forged of course, does say that :)

So, beside some general mumbo jumbo about Dell being used (hehe), what are the exact hardware specs? And also, is there more than one server powering the lot?

@hypocrisy, I know their distro preferences and the software stack. ;) Lets see if they're willing to let us know more.

@BUGabundo I just did a whois on the IP-address myself :( :P

@mandri I ask because I'm curious if the software driving the lot is able to scale in an "easy" way, and then if the site can be segmented up in a cluster solution alá Hsphere.

@hypocrisy, I think it depends on Midgard. @Bergie or @tepheikk, any comments on this?

I'm no expert on this, but I've seen clusters and caching proxies. For sure you can host the DB on a separate machine. The site is using GUIDs as you can see from the URLs. Theoretically having two frontends could work, but I'm not sure of the possible complications.

@mandrl thanks to Midgard's replication features you can also split the system up between front-end web service and back-end processing nodes, or even have "shared nothing" front end nodes.

At the moment I think Qaiku runs on a single server, but scaling up from there has some known recipies :-)

Yup, Qaiku atm runs on a single dedicated server, and scaling up, if needed, should not be a problem as we have some experience on this things :)
