i've noticed when i get attacked or when i attack a Town Shiled is deployed (at no cost when it was on myself) for 12-16 hours. In an 9 hours period i was attacked twice.
I am wondering when this shield is deployed after an attack or if it's possible for 2 people to attack one town at the same time.

The automatic shield is deployed when certain conditions are met:
For the most part, you'll see shields deployed when you lose a battle, as opposed to a successful defense. There are some corner cases (ie, Town Hall intact and 40-49% of the buildings destroyed) where you can both win and get a shield.
As far as I know, there's only one raid allowed on your town at a time. Thus, if you trigger an automatic shield as a result of a raid, you should be granted immediate protection against further raids.
