Linux uptimes comparable with Solaris on busy sites

Comparisons of mean time between reboots on Linux and Solaris are very topical, as the two are often thrown head to head in cost benefit analysis of server platforms. It is interesting to review the uptimes of some of the internet’s busier servers hosted at Sun, Google and Akamai. Perhaps the most remarkable thing is how few reboots there are on the networks, given the amount of traffic they see, though in absolute numbers the average number of days between reboots is higher at Sun than either of the two Linux based companies.
