This can happen even with a single instance oracle. However if a someone is too serious about availability and important of data, he would never hire an unskilled DBA. So this question does not arise.

Few of them had. But they are related to hardware and the third party related issues. None of them are realted to RAC. Few of them have 8k to 10k online users ( A centralized banking database serving around 1000+ branches across the country in Banking environment, processing around 4K CDRs per second in a telecom domain).
In fact having a RAC instance saves many of them in avoiding un-planned outages. At least one instance available all the times and the business does not suffer because of the data un-availability. I can not imagine their situation if they don't have a RAC during those times !!

BTW it was an issue in early days like all other softwares. But things are getting better day by day. I started with Oracle 8 OPS and had a very very bad experience. Things improved with 8i CR server and now it is much better with wire-transfer of blocks. IMHO RAC is one of the best things oracle has built in recent days !
