If you have 2 pcs in a network, and those 2 pcs have 1 chance out of 10 to reach a given datacenter, you have thus 1 chance out of 100 to have both PCs connected to the same datacenter... which explains the differences.

The chance that both PCs are connected to the same datacenter, is still 1 out of 10.

<added> ...because it does not matter, which datacenter is used by the first pc. </added>
