Greetings,
There will be an extended downtime on Wednesday, 3 February to carry out database maintenance work originally planned for last week.
We expect Tranquility to be back accepting connections by 11:45 UTC at the latest, but I will notify you if the live servers are back sooner via updates in this thread and EVE Status Twitter.
Be advised that the authentication and web services will not be available during this period.
Thank you!
