I joined live yesterday as well but i cant connect anymore after my first time. Everything was workin fine, my console is unmodded plus account is ok and network test passes everytime, still cant connect dunno why, maybe tmnet problem.  anyone else havin problem connectin to live recently? Mine says " Live signup is not available at the moment, please try again later "   

Hmm, if that's the case, what country should I opt for when I'm signing up?

Maybe the experts can help me with the pro and cons?

regarding servers and lag... it makes no difference if u choose US, Singapore or Uganda... the XB live servers are in the US, in unknown locations (they think it's cool to make it secret, mission impossible / james bond konon ). well, one might argue that since the locations are secret, who knows there might be XB Live servers in SG? the thing is, XB Live server locations don't matter... it's the players' location that do.

XB Live is merely a match-making service; games don't happen on the server, players host the game (thus becoming the game server), other players join this game, ala P2P... XB Live just point a lonely gamer to other lonely gamers (this sounds, oh so ghey!). after match-making, it's the players' connection to each other that determine latency...

the reasons u should be considering before choosing a region are: download content availability, payment options, ability to purchase MS points. 

US has alot of content but problem buying MS Points (for us malaysians)
vs
SG has no problem on purchasing MS Points but not much content (no TV shows )

*ps: i cant confirm this but there are reports saying that u currently can use asian ms points card to reload a us account... anyone can confirm whether this still work?
