Daily downtime
When is the daily server downtime, how does it affect my gameplay and why is it necessary?
As a result of CCP's attempt to create one large server for everyone to play on, the EVE server requires a certain amount of periodic maintenance. As a result, there is an official daily downtime from 11:00 to 12:00 GMT every day (though it may at times be shorter).
a single hour a day(this for yo flamers except greater patches/hot-fixes which still makes in an average of an hour a day )
