Jean Davies: According to the post which has appeared below yours, the transmitter has resumed service at 16:06 this afternoon. Since this website has no connection with any transmitter company or broadcaster, we don't have any more information on faults or engineering work than that provided in the transmitter engineering posts which take their source from a feed on the BBC engineering website.
