The setup at JINX is a single-machine installation, Intel E3-1220 v6,
32G memory, 8x4T drives. For new installations, we'd probably prefer
more memory -- we have at least 128G in the newer mirrors. We need at
least 12T usable space. We like mirrored pairs for both reliability and
disk I/O parallelism.
We need naked internet - legacy and IPv6. For single-machine
installations, we usually get a /28 on the 20th century internet and a
/64 on the 21st century internet. In most sites, we rarely fill a 1G
circuit.
There's a somewhat detailed writeup here:
https://wiki.freebsd.org/Teams/clusteradm/generic-mirror-layout
We manage the entire system. We only need local support if hardware
breaks.
The ZA mirror is fairly lightly loaded, and is well connected to most of
southern Africa. I see 50-60ms latency from machines in TZ and KE and
downloads at 40ish Mbit/s. I don't think another mirror in ZA would add
much value.
I don't have as convenient ways to test in northern/western Africa, but
I would be surprised if the situation weren't much worse... I'd love a
mirror in e.g. Lagos, Accra, or Dakar for faster downloads there.
