Akamai server reliability

[Roy]

Hi,
Many moons ago, we got a set of Akamai servers.  Over the years I think 
they replaced every one of them at least once.  Last August we got a 
another set of servers due to a move and now two of those three servers 
have failed. 

I still have the original server that started garlic.com in production 
after 11+ years so I know servers can last a long time.  I don't 
understand why Akamai failure rates are so high

Is anyone else seeing high failure rates of Akamai servers at their 
facilities?
