When you say it is down what is the website doing? I was in my account yesterday on the website on my laptop and was able to get in. Earlier in the week I was checking on something on my account and got a 402 error on the page, I tried clearing the cached photos and files but that didn't work. The next step I did was clear cookies and that worked, I hate doing this step because it clear all my other websites that I have auto sign in on and have to but at least now I have those set up for saved passwords now. By clearing cookies it clears the older page versions that it might be trying to load to save time.
Another thing I found was that once I sign in my name and password on the website and the icons where you get the different face gestures that Visible put in place of the spinning circle for signing in, I have had it go into a loop and never sign in, if it does this for more than say 45 seconds I just hit reload and it signs me in right away.
If it is a 502 error than yes that could be something wrong with the Visible server.
