Attack Block

An attack block is sometimes put in place by GameForge. While it is affect, it will stop anyone from starting an attack.

Scenarios
Attack blocks happen in the following situations:
 * When significant server maintenance takes place, such as migrating to new servers.
 * If a significant number of players are having trouble accessing their accounts, but others can get in just fine. This keeps those who can access the server from taking unfair advantage of others who cannot connect and Fleetsaving.

There may be others as well.

In-game message
The in-game message may say something like: "'The attack block is active till dd.mm.yyyy hh:mm:ss. In that time only friendly fleets can be started.'"
