Last week, I estimated that Facebook now had 50,000 servers in Facebook Software Use. Rich Miller of Datacenter Knowledge actually managed to sleuth out the accurate server count in: Facebook Server Count: 60,000 or more.
He took Tom Cook’s Velocity 2010 talk from last week that showed growth without absolute numbers. But Rich noticed it did have dates and Facebook had previously released the server count of 30k servers at a known data. With the curve and the previous calibration point, we have the number: 60,000. Not really that large but the growth rate is amazing. Good sleuthing Rich.
