For those interested in technical details here is a hardware overview of the installation:
150 HP DL165s dual quad-core AMD 2354 processors 2GB-4GB RAM
50 HP DL365s dual dual-core AMD 2218 processors 4GB-16GB RAM
5 HP DL185s dual quad-core AMD 2354 processors 4GB RAM
And here is a graph of what the current CPU usage looks like across about 700 CPU cores. As you can see there is plenty of idle CPU for those big spikes or in case one of the other 2 data centers fail and we have to route more traffic to this one.

Thanks Dhaval, reposted it there
I see you’re using munin to gather your data. how do you sum up the values? in the munin config file or is there some automagic way? is a pain to add each new server to the sum paragraphs in the munin file – that’s how we do it atm.
Amazing, but how do they afford to keep this running, wp service is a free one after all…
