Handling Failures

Our major point of failure is the signalling server. To recap, the signalling server handles co-ordination of peers and the meeting rooms. We have hosted 3 signalling servers on amazon ec2 instances. We have set up the servers to do a fail over - if one fails, the next one takes over.

If a signalling server goes down, before a peer to peer connection is established, then the users that load the page won't be able to see any meeting rooms. If the server goes down afterwards, then there's no problem as the connection between peers has already been established.
