mail.zoho.com unavailable

Hello,

Since few weeks I have this problem, http://mail.zoho.com is unavailable through HTTP, but the service works through POP3. I have the same problem at home and at work. Also, I can't ping the server.

Does anyone have any idea what could be the problem? I don't use any proxies and the nerwork in my work does not use any filtering software. Thanks in advance for info.
