Troubles logging into our Live account

All was just fine up until today afternoon. When we try logging into our Live account sometimes we are able to and sometimes we get "access denied" page. When we are able to log in, clicking on Devices or Rewards results in either 'Oops, something went
wrong' or 'Access denied'. What gives? We haven't changed anything regarding devices we're using to access our Live account. No new software, no new firewall rules, nothing. Can someone from Microsoft check on your end what's going on? By the way, logging
into our Xbox account works just fine, but going from there to our Live Account page results in same beforementioned errors.
