I had the same issue. But after a couple of days it spread to my whole system but I don't know that it was related as due to storms in AZ this year I have lost power and internet many times. This time I didn't actually lose it but it sure was not working correctly and I could not access several of my regular forums and websites for a couple of days.
I could not get my emails or any contact that I normally make through the internet. When it cleared up the AWS Members Only Forum was back to normal. Who knows the mind of computers and the internet. Cyberspace is the largest black hole ever discovered by man.
Have a Great Day and a Fabulous Weekend. Brent
