Er... Except they announced the downtime yesterday, and specifically said both the website and the game servers would be down.
I saw about the website, it specifically said gameplay would not be affected.
"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".
