Libravatar's images are automatically served by a network of mirrors (through DNS round-robin).
List of mirrors
To get the latest list of mirrors on a UNIX machine, run:
for HTTP IPv4 mirrors and:
dig AAAA seccdn.libravatar.org
for HTTPS IPv6 mirrors.
Become a mirror
If you have a server with some spare disk space and bandwidth, please consider supporting the project by running a mirror.
At the moment, it consists of installing a Debian package which takes care of setting up Apache and receives regular updates via rsync.
