Most disconnections related to Live Chess have nothing to do with server maintenance or server outages. It has to do with problems with the beta implementation, sometimes exacerbated by the use of a particular browser, sometimes even one's local connection issues.
For Chess.com:
I'd like to give a comment for the disconnection that was being encountered of most players! I'd like to say that why don't you give us a Confirmation wherein we are going to be disconnected! In terms of minutes!
