GPG-Servo has asked me to make a full list of people who has set up a mirror for the Vault archieves. If you already have a working mirror running, fully or partly, please either PM me with a link to the mirror and also mention if you are hosting only mods or maps or in the very near future, replays only.

If you are interested hosting a mirror of the vault and don't know how to do it, feel free to send a private message to GPG-Servo (preferred) or contact him via email at gpg-servo@gaspowered.com.

I will be adding mirror links to this very post as soon as they start to come in, and update it along the way.
