Quote from Eurogamer :
  
"The announcement came via a Tweet from Xbox's European Community Manager Graeme Boyd.

No explanation was offered as to why, but a handful of countries will still be treated to the promotion. Gamers in Russia, Poland, Greece, South Africa, Czech Republic and Hungary: fill your boots.

Everyone else will just have to wait. "I'm told that 'we'll be in a position soon to announce a further Free LIVE Weekend.' Apologies for any inconvenience." Boyd added in a later Tweet."
 
The US is unaffected.
 
Only reason I'm pissed is I was looking forward to the Bulletstorm Demo.

that sucks ass. im a gold member but i usually take the free weekend to play some opportune games of reach/bad company 2 with a few buddies. its after the fact now but i was wondering why he wasnt online 

I totally forgot this was a thing!

That's complete bullshit. I'm a gold member but I like being able to force my friends online when the free weekends come around.
