Strange new screen when trying to access COX webmail regardless of device type

Wow! Today when I try accessing my email on desktop or mobile device, I get a splash screen that says 'Welcome to CCI-RES, R!' And asks for a password. I have not done that. --- Also the web address is now: https://www.cox.com/content/dam/cox/okta/webmail.htm

Is this legit? Are we infected? (But multiple scanners show nothing.)
