First, please don’t quote complete posts, especially if you react to a directly preceding one. There is no need to do so, this is not an e-mail message, the complete history of the conversation is always shown in the same window here.
Second, what I wanted to say by my post is that it is easy to find out whether the issue with access to cloud2.mikrotik.com is real or caused by your own firewall as @DarkNate suggests. And the conclusion is that at least in certain regions, there is a real issue and that it is likely to be at Mikrotik end given that forum.mikrotik.com can be pinged no problem whereas cloud2.mikrotik.com cannot.
So if it causes you a problem, open a support ticket with Mikrotik, either by sending an e-mail to support@mikrotik.com or, better, by using the web interface. forum.mikrotik.com is a self-help forum of fellow users, not an official input channel of Mikrotik support. You can refer to this forum topic in the ticket.
