"On Thursday January 12th from 6:00AM to 10:00AM PDT (1300 to 1700 UTC) we will be performing scheduled maintenance on the Star Trek Online shards and website. Both will be offline for the duration."
That's the ENTIRETY of the announcement yesterday. It clearly says the shards will be "offline for the duration".
The problem with that announcement was that the date in the thread title was the 11th. Since there WAS maintenance on the 11th, I didn't bother to read it yesterday.
