Is there an issue with dub-m.hotmail.com etc... as I cannot sync my mail on either windows 8 or WP8, on win8 I get "email-address is unavailable" on WP8 I get "we're having a problem connecting to dub-m.hotmail.com"

I'm just wondering if there is an outage with the exchange server<s> as I can access email etc.. on the web just not no 2 PCs or my WP8.
