Yes Igor is right. I've noticed this few times before, but it was temporary and after few hours everything went back to normal. Last few days, actually, whole week, nothing is going back to normal. It's really annoying when you click on some thread and you have to wait like 1-3 minutes for a page to open... don't even wanna mention what's happening when you are trying to search for some post, or maybe reply to someone's thread...
