I don't know anything about internet connectivity in Myanmar, but it's probably spotty at best outside Rangoon. I'd have called the Embassy, but it's getting a little late for that now. There can't be many Americans in Myanmar and you might even have scored an invitation to watch the game with the night watch (our embassies have incredible communications capabilities), if you're in country on business that is of value or interest to the US. If you're just there as a tourist, not so much.
