Unable to verify new password for hotmail/outlook on ipad. Then, for internet, I get message “server not responding” .

As noted above, suddenly found emails not updating this morning.  Recently changed password (I think I had several days of things working ok, although I generally check emails elsewhere).  Could not verify email password this morning.  Then could not access internet-or apps.  Get message that "server not responding" but no other computers, phones or tablets in my house have any problem!  Any ideas?
