Maxis is holding a second closed beta on February 16, 2003.  According to Maxis’ FAQ, this beta test is scheduled to last only 24 hours and is mainly for the purpose of testing the servers.

We have added more capacity to our servers in order to accommodate the flow of players. This beta will help us stress test them.
