I booked with TID for an overseas trip recently and they specifically told me that any delays and cancellations that were due to the airline's fault was not covered by them; I did look at a few other insurance companies and they were all the same.
I've been told that the Navitare data center is having issues and a few other carriers are also affected (not sure who else apart from Virgin, Jetstar use Naivtare)

Call the GCC, they will honor the internet fares as you are unable to do this online.
