I see no unanimous complaints, so it could be that it's only at my place where a bit of havoc is created.
Page opening, switching, even refreshing takes ages. Sometimes the front page lay-out looks disfigured. At one time the tool bar disappeared although when I checked I found I was still logged in. But even the Inlog page has a basic look, like it was stripped from html. Front page now looks OK again, but transmissions still are slow.
It all happened in the middle of correcting a blog post. A minute ago I tossed my cookies, cleaned up my register, checked a few other things, can't image what I could have done wrong.
...right this moment, while typing in my forum post, this Support page switched to an altogether different lay-out. Creepy!
