2 degrees cell data network issues or my phone?

Hi

I have had a couple of intermittent data dropouts on my Nexus 5x, but this morning I have no data network at all. Restarting the phone has done nothing. I know I have data in my account as it shows I have 1100 mb available in the My 2 degrees app when it eventually logged in. I can see in the 2 degrees status page something is under repair, but not what.

Is this possibly related to the big mess happening with the system switchover still, or should I be looking at my phone?

Thanks

Paul
