Upcoming maintenance, August 22-24th

Hi,

I got the email "Upcoming maintenance from August 22 through August 24 will affect deployments of Microsoft Azure Virtual Machines and Cloud Services.".

The email doesn't make it clear if I should be expecting 30-45 minutes downtime or 12 hours... surely not the latter?

Also - how does this affect Azure websites on the Standard package?  Is the Azure fabric clever enough to move the websites onto another machine and therefore avoid any significant impact?

Any guidance would be appreciated.  Just starting out with our production systems live on Azure.

Thanks,

Justin
