Don't know if you saw this from Sparklepony:
If you are seeing a "Client Bandwidth Exceeded" or a "Socket Closed" message when you try to access your vineyard or your neighbor's vineyard, this is because that vineyard has too many objects in it. We are currently working on a fix for this issue, but at this time there is no way to access the vineyard.
You do not have to contact technical support about this, because we are already aware of this issue and are working on a fix that will give you access to the vineyard.
Thanks to everyone who has reported this.
