AWS (Amazon Web Services), our Data Center provider is experiencing problems, and have updated their dashboard to indicate as such. We are monitoring the situation.
The issue is with connectivity, so one minute everything maybe working great for you, but a second later you will get a red logo or the admin site won't load.
DO NOT REBOOT YOUR POS!, keep selling with Red Logo. If you reboot you may need to re-activate which is impossible while AWS is down.
