The TW status page has a log of this problem. Looks like it might just be TW.
I think TW's feeds of the terrestrial channels are sourced from DTT locally (as apposed to most channels that come from the national headend), but where are the received. Their building at the Gyle doesn't seem to have any aerials on it. I presume it drops back to a feed from the national net if the dtt fails.
