A few minutes later, Steam is back up and running. Everything should be back to normal!
Unknown cause. Steam normally has around 5 minutes of planned downtime around this time of day on a Tuesday but it's Wednesday so this seems unplanned and might last a little longer. The extent of the effect on PSO2 is not fully known, but:
- If using the Steam version you may be unable to log in temporarily
- Achievements won't work until it is back up and running
- If you're still downloading the game on Steam, that download will probably freeze until the connection is restored
