My IP has been blocked from Zoho domain

Most people complain of IP blacklisting from an email client perspective, but mine is where my public IP has been blacklisted from the Zoho domain as a whole.

That said, I noticed my email client chowing errors on my Zoho account and didn't think much of it, until I tried to logion Zoho on the web and found that I was not able to access the zoho.com domain from any machine on my network. This all went-away after launching a VPN client, which is fine, though not helpful as I cannot perform my day to say task through a VPN.

That said, I sent off an email to support on this, but have yet to received a response, not even an automated one, though I would like to know what lead to having my IP blacklisted from the zoho.com domain entirely, or why this would even happen...
