Hmm anyone know if an over the air software update was performed by Sky last night? And what was it for?

My Multiroom Sky boxes were reporting no signal this morning.  I have them on a dual output LNB, 1 output for freeview the other via splitter for both sky boxes, DS230 and DSR2000
I had to go into the DSR230 menu and swap around the settings which controlled the power and local oscillator switching to the DSR2000 and change the DS230 to no power etc...
Upon rebooting the DSR2000 it began a software update, which completed and rebooted.  Got service back once this happened.
