The server is coming online now. A few points to note:

If you had the client and launcher open already, please close the client (the launcher will auto-close when you do) and start again from the launcher. A small update will download and you'll be good to go.

For anyone wanting to multibox, please refer to https://shardsofbritannia.com/play for details. We are working to improve the method to launch multiple client instances and will advise further when that's done.

Thank you all for your patience once again.
