Another data point from a startup, we have a few people also globally distributed on on-call, we use each other as backups in case as the commenter suggested you're drunk at a bar or camping. Our site doesn't break much (haven't had an incident for over a month now, maybe something happens once every 1-3 months and it's usually not severe) and we have redundancy in the schedule so we've come to not feel so neurotic about it.
