At approximately 21:02 we experienced a a mass disconnect of clients from Tranquility. Players should now be able to log back in and we are investigating the cause however it does not appear at this stage that this was an issue with our infrastructure. We will keep you updated both here on the EVE Status Twitter account.
Anyone who lost ships due to disconnections can submit a ticket at http://support.eveonline.com under the Game Play Support -> Reimbursement -> Lost Ships category and they will be investigated by our hard working Customer Support team.
