Certainly in the IOM it was just an unfortunate afternoon. Only one cancellation which was the MAN and a few delays in the evening sectors.
You only need an hour delay for it to mess up onward connection plans and with the exception of the STN the delays in the evening were mostly an hour give or take a few minutes. Delays therefore were not excessive, just a few at the same time and on routes where delays can be more inconvenient than others.
BHX was a similar story in that apart from the morning EDI was cancelled. It went a bit messy in the afternoon....I suspect some link to the late morning EGC which had an hour delay didn't help and caused a knock on delay to other sectors. On a Saturday at most airports if you start of with a small delay it just grows and grows.
MAN had more cancellations so was worst hit during the day. Two IOM sectors, a DUS and some others were cancelled.
The majority of the day in SOU and BHD was trouble free with the odd delay here and there which I suspect was caused by aircraft changes to assist with the wider network problems.
EXT and BOH was trouble free all day and CWL only had one minor delay.
