Travelling in Mauritania, cannot log into icloud with my PC netbook. I can read my mail on my iphone, but I get a message that "icould is not available" when I try to open it on the PC. It's very annoying as it's not so easy to type on iphone!

Been looking for similar posts, surprised I haven't found more, because I'm fairly certain that there is a current problem with some parts of Apple's server network: I have 3 iCloud accounts in Mail on my Macbook, and 1 of them (annoyingly, my main one) has not been able to connect for an hour or two. And both of the others wouldn't connect for a few minutes, but are now working again.

More suprising is that trying to log in to webmail (www.icloud.com) is giving a very unhelpful error message, suggesting the server is down. Everything else Internet is working fine for me, and haven't changed any settings, so fairly sure problem is Apple's end.

It's possible that your iPhone is collecting your mail via a different server route that is still working; my three iCloud accounts are collecting via p02.imap.mail.me.com, p09.imap.mail.me.com and p99.imap.mail.me.com, and it's only p02 that's consistantly not working.

Ah - all back up now (offending mail server and iCloud.com), and found the following thread which seems to explain my problem at least:
