Price anyone?
Rackspace don't really do inflated acquisitions - they paid $18M for Slicehost and Jungledisk (combined). Cloudkick raised $2M back in April, so you would think that the price would be more around $15-20M.
Either way, congratulations to the team, RS and to YC. CK is a great product.
They target at 10x so that with their spread of total-failures/so-sos/big-exits they end up making a nice return.
Plus there is always Pingdom, AlertFox, Webmetrics, Keynote...
