Only one upstream

Sometime ago there was a "scheduled maintenance" outage and when service resumed I only had 1 upstream channel. On posting on the VM forums I was advised that the other channel would eventually appear.

It doesn't cause any problems upload is as fast as ever
I am on 152Mb service.

I just wonder whether to moan at VM again?
