WTF Cloud got to do with it?
I can see that putting it in the cloud loses you access if te Internet falls over. But the internet doesn't have to fall over.
Back in my Telewest days we, in response to failures by people ike Level 3, put in resilient links with different providers, through different geographic touchpoints. It wasn't perfect but we could keep soomething going if Level 3 or Telecity went down when previously we just had to look at the queue on the phones and shrug.
Hopefully thhings are less reliant on the two of tem since the old days.
