This is an overview of our currently deployed and active cache hardware at the Traffic layer.
Deployed Hardware Classes
We have purchased and retired multiple classes of server hardware over the years in staggered timeframes. In the general case we'll always have multiple overlapping classes of hardware as various warranty and support periods expire. These are the currently-active hardware configuration classes:
