MSN unstable today?

I am not sure whether any of you facing the same problem; but somehow I couldn't login to MSN for more than 10 minutes.
The error message is always the MSN lost the connection....
I am not sure whether this is my network connection here at work; but don't think so...else I won't be able to access all the websites....
Hmmmm......
Why is it unstable...beats me...probably the server...
