For a few months, I considered using the mirror service from Fosshost in userrepository.eu. The service results from a partnership between Fosshost and Fastly, giving projects access to several PoP’s around the globe.
Finally, a few days ago, I enabled the service. I also created a package with the mirror’s list, userrepository-mirrors, available in my repository and AUR. The package has all the instructions for enabling the mirrors and what to do if you already have userrepository in your /etc/pacman.conf configuration.
The mirror service syncs every 4 hours. After each build, partial or full, the updated packages will be pushed to the servers with rsync.
If you’re wondering why it took me so long, the answer is simple: fibromyalgia and pain 24/7.
