Was on NA east 2 earlier, sent a total of 500k in gifts to a second city of mine and nothing has since arrived a few hours later. My girlfriend also can't buy any power from me despite having over 200MW excess in my main town. It says she's buying 0 MW even though she's short a good 50 MW or so. Something is definitely wrong with that server.
If the server goes down or is disconected from your game it will not take effect until the server is reconnected to your game to update it seems.
Watch the warning messages about that on the top left of your games.
Also buying power from a neighboring city only seems to last a day or a week at the most right now in actual game play time.
I exchanged power between 2 of my cities and it automaticly shut off before I noticed how long it lasted in game time.
But it takes a server conection to update certain things you do in the game.
