I'm suddenly getting minute by minute alerts for duplicate file uploads. I'm using hg612 stats. Are they real? Nothing has changed at my end!
Yes, they are very real else you wouldn't have been sent them...
After trawling through the database here I can tell you exactly what happened but not why.
You didn't upload anything between approx 25 March 18:00 through to approx 30th March 20:00. On the 25th your local clock was correct on GMT. When uploads resumed on the 30th, your local clock had jumped forwards 2 hours (rather than 1 hour after the clock change to BST on the 29th) but no idea why. It stayed like that until 17:49 this evening when it abruptly lost an hour (again no idea why) and was back on BST as it should be.
So that meant that for the next hour, you were uploading stats that you had already uploaded, hence the duplicate messages. They would have stopped at 18:49 had you not stopped uploading yourself at 18:47....
Please remember that MDWS is just recording the data you are uploading, it doesn't modify it in any way.
