Show me an email account that isn't in a cloud somewhere.
Exactly! Cloud based servers are nothing new.
Though if you consider the internet new then I guess it is.
Companies have just started to use the cloud for software more.
Why? Because it is easier and cheaper to create and manage the software.
Even Cloud based HA isn't new, more and more people are just using it. The same old issues with cloud based servers still exist. When they go down if your using it your down.
With Alexa, Amazon cloud servers are just as venerable.
She has been down a number of times on me though this doesn't affect my HA, only voice activation using my Dots. My HA info is stored locally as well with Alex10, AHP, and a few other HA programs.
There are some companies still selling HA stuff which are solely cloud based controlled.
When their cloud goes down there is a big up roar.
Remember when the Nest cloud went down?
Luckily no one froze to death.
No one gives a second thought when a email server goes down.
Though when your using it for HA it is different.
Usually servers aren't down for long unless a company goes under.
