As shown in my article “A small CDN for my Mastodon instance metalhead.club,” I like to use CNAMEs to organize my DNS entries. I usually create a DNS record for each host that maps its hostname to the IP. Then I use one or more CNAME entries to link certain (sub)domains to these CNAMEs depending on the service and purpose. This helps with overview and can make organization easier—especially if IP addresses for hosts need to be changed.
Since the big Twitter wave that flooded the Mastodon network and, more broadly, the Fediverse in the fall and winter of 2022, international users have been playing a bigger role for metalhead.club. The service is hosted entirely in Germany, and that was still the case until recently. However, with the increasing number of international members come new challenges: for example, the rapid delivery of content.
As long as users are mainly located in Germany and Europe, latency times to the “Full Metal Server” in Frankfurt are low.
