As most of you might have noticed, the GameSpy shutdown is not in effect yet.
According to EA and the producers of Battlefield, they plan to make an update
of their games to keep the multiplayer game running. Most likely EA pushed
GameSpy successor "Glu Mobile" to continue the service of the master servers.
Unfortunately, there are no news about MoHAA. A few weeks ago, EA made
a statement that they "are still investigating community-supported options
to preserve online functionality for these titles" [1], including MoHAA. As there
are no further news at this point, we still have to plan with the worst-case
which is the shutdown at any time.
