> If a url is not available to public that does not mean that the url does not exist Compare the behavior of the following URLs: http://cisco.workplace.com/ http://cisco.workplace.com/ http://contoso.workplace.com/ http://contoso.workplace.com/ http://google.workplace.com/ http://google.workplace.com/ Two of these are real companies that have signed up for Workplace. One is not. See if you can tell which is which. Now, which of these does http://instagram.workplace.com/ http://instagram.workplace.com/ seem most like? (Of course, it is possible that Meta has done something special to make their Workspace instance behave exactly like a nonexistent one. I can't rule that out. But it would be very unusual for them to build in a confusing special case just for themselves.)
