iCloud Mail not working or not responding

My iCloud Mail does not work, not on my iPhone, nor on my Mac or iCloud.com . On iCloud.com it says "Can't load Mail." on my Mac it says "Trying to login to this iCloud IMAP account failed." and on my iPhone it says "iCloud Mail server is down".

Update: It now works after around 15-20 minutes.

P.S. Hope it doesn't happen again.

Another Question: I have a @me.com Email from Apple that i still use, will apple once delete @me.com emails from whoever has it still or i can continue using it without worries ?

Thanks to the Apple Community.
