“Sorry, there seems to be a problem with Hotmail right now…” came up on my account this morning. How can I fix this (Feb. 21/2013)?

Hi there, I have been trying to login to my hotmail account since yesterday.  I have tried clearing the cache, and have tried 2 different computers with no success (including Firefox, Safari, and Internet Explorer).  This message keeps on coming up.  How can I fix this?  I really need to my e-mail up and running today for work.  Thanks.
