Thanks for the replies. To clarify, my Instant Notification Service is set to notify me of events within a 30 mile radius (and I've just re-checked this to make sure it is still enabled, which it is), yet I'm not receiving notifications when the event is first published. However, I'm intermittently getting posts about the event which the CO's posts in the few days leading up to the event (eg, last minute details) and post after the event (eg CO thanking people for attending). I still get notification of other types of new cache, and up until about 8 months ago, I was getting new Event cache notifications. I've not changed anything that could explain this (i.e. still with same Internet Service Provider, still using same email address) so I'm at a loss as to what is, or rather isn't, happening. Only thing I can think is that there is some problem at Groundspeak's end.
