A core system had an expired domain record. No build needs to be deployed. In some cases, it make take a little longer for your game to begin working again due to DNS propagation, but in most cases it should start working again immediately. If you are already in game, the game will begin syncing. If you are in the main menu, you might want to restart the game eventually waits some time between connection attempts. You can also flush your DNS to expedite the process (warning: this is an advanced maneuver).
Apologies for the outage, many of our team worked throughout the night to resolve it. It ended up being down for between 12-24 hours depending on your DNS.
We have deployed the experimental yesterday (separate to the outage) which has significant performance improvements and includes our initial work on dynamic missions for open-world.
If you still have issues connecting at the main menu:
- Try doing a "flushdns"
- Try restart your router and/or modem if you have them separated.
- If that does not work, switch your PC to use for example google's DNS
