automation makes both easier to deal with.
"Mean time to repair" is all fine if you don't have to drive 30 minutes to datacenter to swap out stuff.
Even if its cloudy cloud and you have backups, restores can take a lot of time.
Also you will want HA when it's your internet gateway to die
There are also levels of implementation. Making fully redundant set of loadbalancers is relatively easy. But any stateful app is much, much harder. In case of applications active-passive type of setups are also much easier than full on active active redundancy, especially if app wasn't written for it.
