Where did you see that message? When did it happen? What were you trying to do when the message appeared? Any screenshots?

There doesn't seem to be anything wrong on our end.

Maybe you were trying to perform too many actions in a relatively short time span. Try to avoid posting too many threads in a row. Or, it could simply be that your connection was having bad latency to our servers, in which case you should just retry again after some time. If the problem persists, maybe your connection simply has bad peering quality to our servers. This isn't something we can alleviate as certain parts of the world get poor connections to anywhere outside the area.

The site has been performing very smoothly for me.
