POP Mail error Messages

All my accounts worked on Friday. Late yesterday I started getting connection errors on my POP accounts.
This is both in outlook and on my mobile devices. This tells me that either ZOHO POP servers are not Authenticating correctly or there is a much large issues ZOHO is not commenting on ?

I can access my account remotely at ZOHO mail....so the problem is the POP servers. Can we get a timeline for a fix to this issue ??
