not true, you can have full resiliancy if you plan it right and pay the money, its what i do for customers every day in the server/storage world.
All depends if they want to cut corners, the customers i deal with aren't as big as o2 normally but they wouldn't be satisfied with 24+ hours of downtime for their customers, just wouldn't be acceptable, you want 99.999% uptime though, you need to pay for it.
And yes, I do have to go out sometimes and deal with s**t that happens, but i get paid for it, if i didn't like that aspect of the job, personally i would change job, as that's what i do, if i don't like it i change.
I was supposed to be at a job 9am sunday morning, had to be up at 7, couldn't get out because of the snow, still up early though, but it's my job, i choose to do it so i don't complain when its not a put my feet up and surf for 8 hours during the day jobbie.
I personally don't care whos working on it, it's their job, they have a job and are getting paid, i don't see the issue? But i'd like my service to be up all the time if i pay good money for it personally.
I do spare a thought for the emergency services who have to work xmas day though to keep us safe, thats not a nice job.
