This MUX has been dropping audio on a daily basis now. I thought initially it was the Radio Caroline feed, but it's not, as CDNX on the same MUX also cut out. Sometimes it's a few minutes, yesterday it was off for more than 30 mins.

It switched over to 9B in August and I thought there was going to be a transfer to North London MUX but this doesn't seem to have happened yet.
