Came into work this week after the holidays and was an email from azure saying unless we redeploy our virtual machines before next week they will do it at midnight utc - which happens to be mid-day here.

No problem I just email our client and schedule a time Friday afternoon where the servers will be unavailable and I'll do it then.

Today (Thursday) azure email and say they are going to just reboot our servers now. I check and the application is not working. Clients start phoning in saying they cant access the system..
