I just went from not signed in, to signed in, and it would not sign me in for over a minute, then said "ooops we are having a problem" and the screen went white. This is what I deal with all the time. If I am logged in, it will not load a page quickly, and often just goes to a blank screen. If I am not logged in, it works great, and often just browse without being signed in. No matter where I am, or what device, it makes no difference. I have tried at work, at my VT house, on my phone, on my tablet, it makes no difference.
