[General question] Microinterruptions of Youtube

Hi all.
In the last weeks I suffer a drawback about Youtube. When I watch a video
there are sometimes several microinterruptions of the sound (and sometimes
even of the images). Those microinterruptions are annoying and unbearable
for me.
I'd want to know if that happens even to other people.
I am trying to understand, as the first step, if that happens because of the
server of Youtube.
