For instance, in highly distributed systems like DNS, it makes no sense to upgrade the hardware if it isn't *absolutely* necessary. Two of these three are using 1st gen Compaq 1U Servers ("360" IIRC) for some of their critical infrastructure. I have worked at 3 of the Big-5 NSP/ISP's in the U.S., and the situation is the same at all of them: CAPEX hasn't been truly easy to get since 2003/2004, and as a result, some servers are kept until they literally *melt*. I realize that every company I have ever worked for will deny what I am going to say, but.
