Refreshing the page or going hotmail.com freshly gives different error almost every time.
Like:
Internal Server Error – Read
The server encountered an internal error or misconfiguration and was unable to complete your request.Reference #3.ac18ae8c.1341592655.3c69f1e
And
Service Unavailable
HTTP Error 503. The service is unavailable.
Etc.
What’s the error that you’re receiving while trying to login to hotmail ?
