instagram.workplace.com redirects to www.workplace.com

Any other legit domains take you to their SSO page. Try walmart.workplace.com

Seems any invalid subdomain causes a redirect to the www subdomain: asdfgqwerty.workplace.com

workplace.com is owned by Meta. So who knows if they are running their own intranet instance for themselves. They dont need to pay big bucks to anyone to cause a fake redirect.
