Start with the shared service before spending time changing your own setup.<\/p>\n<h2 id=\"does-the-error-mean-the-servers-are-down\">Does the error mean the servers are down?<\/h2>\n<p>During beta testing, the error accompanied build outages on <strong>September 17<\/strong>, September 24, October 1 and October 8; on October 8, it continued briefly after the realm was reported online. Those incidents explain why a disconnect message alone is a poor reason to reinstall.<\/p>\n<p>The error also appeared in an <strong>October 28<\/strong> <a href=\"https:\/\/epiccarry.com\/blogs\/wow-forever-name-reservation-date\/\" target=\"_blank\" rel=\"noopener noreferrer\">name-reservation<\/a> discussion, where players were advised to launch Forever rather than the Beta client.
