# Please use a mirror geographically close to you for initial sync,

#
# Note that local mirrors may be faster
# Running rsync from the main "rsync://rpms.remirepo.net" requires
# the source IPv4 and IPv6 addresses to be allowed by Remi. Please contact
# Remi at remi@remirepo.net to get the process started.
#
# A complete list of mirrors can be found at
# https://rpms.remirepo.net/
