Yes... For the most part, my company has given up, and has entire Fault tolerant clusters and farms with on-site spares for key systems, and are progressing to full geographically dispersed High Availability (Dual active where possible)
I know many can't afford that level of Fault Tollerance, but you'd be surprised how inexpensive on-site spares are compared to the cost of 4 hour support over time.
