I checked in earlier today and have noticed no changes in either traffic or anything else. It has made no sense for many, many reasons so I just assume it is a technical difficulty.
It is a little worrying and it would be reassuring if HubPages let us know when there are these difficulties because I am still not sure what is going on. I hope someone posts something here to elucidate things.
I have just finished checking my stats again and noticed a small change but there seems to have been many hours when there was no changes. It seems to me that there could be some kind of anomaly but I would have thought others would be reporting a problem.
It is all quite puzzling and I wish I could throw more light on the problem.
