This mirror is located on the campus of James Madison University in the Shenandoah Valley of Virginia. There are two servers behind mirror.cs.jmu.edu to provide a better level of availability. The configuration of both servers is identical:

  • Dell PowerEdge R720
    • (2) x dual-core Intel Xeon E5-2660 @ 2.20GHz
    • 64GB memory
    • 1GbE network connectivity
    • 3.6TB storage capacity
    • OS: Ubuntu Linux 16.04

Custom software is used to keep the servers in sync with upstream and with each other.
