We use Duo at work for 2fa. I am laughing my ass off, I literally can't do anything -- can't get on the VPN, can't get into my emails, can't access company services. They locked everything down so hard, they've literally chained themselves to a radiator and tossed the key out of reach. We didn't receive internal communications about the outage yet -- and my bet is it's because whoever's in charge of that, is locked out due to the outage.
