Servers are organised in datacenters - Elemental, Gaia and Mana for japan; Aether and Primal for NA and Chaos for the EU. Each datacenter is made up off several servers - Siren and Cactuar (the OPs server, according to the forum at least) both belong to Aether, so the two of you could get paired with each other! My server, Odin, is part of Chaos - since we dont share a datacenter, we'll never be able to play with each other (unless someone transfers, makes an alt etc.)

Other than that there is nothing that determines with whom you get paired in normal DF - not even your blacklist matters.
Its a bit different for the savage and ex-primal stuff, since you can set certain filters such as "duty complete" that will only pair you with people who cleared the content in question before.

But in general you can be matched with anyone from your datacenter, there are no filters beside healer/tank/dd.
