iCloud email error: Connections to the server “p25-imap.mail.me.com” on the default ports timed out.

In Mail , my iCloud account on all my Macs have a triangle and "!". Clicking on the triangle yields the following: Connections to the server “p25-imap.mail.me.com” on the default ports timed out.

Restarts dont seem to work; and I cannot find a place to verify the server.

Anyone else having this?
