We are aware of an issue which caused Serpensarindi to go offline last night, and have just finished testing a fix for that particular server. We’ll be releasing this fix in approximately 10 minutes, so all servers will be going down for a short period of time - this will not require a client update.
In game client showed “Server Maintenance” for a short while, teens of seconds, maybe a minute. I think a better in game announcement would be something you need to work on, but I agree it’s a low priority right now
