Balmung and Zalera happen to be on the same data center and cluster, so usually if one is having network issues, the other is too.
Occasionally on big patches or expansions, Balmung will get so full that certain maps will become full and lock people out. SE's kinda learned from this and will open another instance of the zone, although you cannot pick which one you get into and it may split parties up. (They'll always announce beforehand or make a maintenance notice when this happens).
Depending on your computer, you may need to turn down graphics settings and/or effects if you notice your frames per second dropping from the large amounts of players though. (FATEs have been known to crash PS3s when it's a popular/event one).
