iFog GmbH operates three mirror servers for Debian 9, 10 and 11 as well as Ubuntu 20.04 and 21.04.
All mirrors are hosted on AS34927 and reachable over IPv4 and IPv6 on local IXPs, peerings and transit.

The mirrors are also available behind mirror.ifog.ch, which holds DNS records for all three servers.
