The ungleich DNS infrastructure¶

Overview¶

• Every place has 2 redundant caching nameservers.
• All zones have 3 authorative nameservers, located in 3 different places
• Important zones (like ungleich.ch) need to be resolvable, even if a place goes offline
  • For this reason some authorative data needs to be on the caching name servers
  • For this reason we stay with a bind9 based setup for the moment (might change in the future)
