Also, sending of emails seems to be a bit delayed as well. From being received by Yahoo (and posted on the website, going by an experience last week), my mail took 1.5 hours to being sent by mail to me. I have checked Yahoo Feedback (https://yahoo.uservoice.com/forums/209451-us-groups/filters/new) and it seems we're not the only once experiencing these problems. And interestingly enough, if you search for the symptoms, it seems to occur every few years (it is very interesting to get search results from 10 years ago describing the same problem with Yahoo Groups).
