Eve voice returned to service (From www.eveonline.com)
Update 23:46 UTC: EVE Voice has returned to service. If you experience issues connecting to EVE Voice, please disable and then re-enable EVE Voice in the ESC menu, or relog into the game with the character in question.
Players are currently unable to connect to EVE Voice due to technical issues our voice provider is experiencing. At this time we do not have an estimated time on when EVE Voice will be back online. We will continue to post updates to this issue in this thread. We apologize for any inconvenience this may have caused.
