I think you are overreacting a little bit. The expectation always was that one or more root servers would be unavailable at any one time - hence why there are 13 different root server systems available. More than one can be unavailable for days, and due to redundancy and caching it won't affect anything - as expected, nobody has really noticed this blip.
There should be a good mix of technologies used in the different root server systems - different architectures, OS, etc. Some sites use anycast which gives massive redundancy within that system as well as providing good performance. However other architectures have their place and may be more robust to attack or certain failures. We need the variety.
So technically it's a shame that H has gone down - they don't seem to have a good track record. Fortunately this time it isn't an issue.
