Clicks stopped increasing?

in the Adsense report

For the last several hours I didn't see any clicks, which is unusual. The impressions are increasing smoothly as usual. Anyone noticed this?

Or is it just the worst day for me?

Clicks are changing for me.

I also had this a few houres ago like you can see in another post in this forum.

Now it seems to be normal again.
