EVE Online says it has taken down its Tranquility server cluster—housing the MMO itself and companion game Dust 514—because of "a significant and sustained distributed denial-of-service attack." Tranquility has been down for 16 hours. At this time, not even EVE's web site is reachable. Follow EVE's Twitter for more.
[Update] The outage is over. "At no time was customer data compromised or accessible in any way," says publisher CCP. "We will be looking at ways to compensate players in both EVE and DUST for the outage and expect to announce what that compensation will be very soon."
