CIC/CHC always maintain in their communication that the E-CAS status does not always reflect the true status.
We have all had a DM before and that turned out to be a bug. So this one may or may not be a bug. Difficult to say anything with absolute certainity.
If it is not a bug, wonder why all of us got DM on the same day ? Why two lines of status ?
Here is another thought to this, may be the techies here can clarify. Their E-cas update system probably has a script to automatically update the status peridocially ( based on the inputs of estimated processing time, BFD's etc ) , hence when the script runs and a null value is found in the new system as the files have not been processed yet, it probably throws a DM automatically. ( Wishful think, I know, ha ha ha )
Anyways, nothing is certain until there is some communication from CIC/CHC regadring this.
Wait....
