Our internet wifi went out on a tangent the other day and nobody new why. After 24 hrs whatever gremlins triggered the failer, it just started working again normally.

We are aware of the issue and our investigating with our service host, it does seem intermittent but happening more often. I have found that selecting Preview and then resubmitting the post resolves the issue for me.
