  4. DNSSEC pros • Authentication of origin • Record's non-existence verification • No MITM and cache poisoning anymore • DANE/TLSA !

  5. DNSSEC cons • Additional maintenance tasks • Increased cost of errors • Target for DDoS - larger responses, more CPU load and RAM usage

  6. Back to other services • Whois - standard and web interfaces • Web interfaces to database updates • E-mail - other way to communicate • NTP stratum 1 server - ntp.amnic.net member of pool.ntp.org • cDNS - an instance of anycast cloud

  7. Hardware, connectivity, etc • Two datacentres • Two upstream NSPs • Two power sources

  8. Datacentres • Server per service - virtualization • Database streaming replication • Internal anycasting • Total logging • Backup to opposite DC

  9. Upstreams • Multihomed, with large capacity • Connected to local exchanges • Native IPv6

  10. Power • Reliable switching between sources • Good UPS systems

  11. Disaster recovery • Migration to alive datacentre • Migration to alive database • Recovery from backup

  12. What to improve • Global anycasting of DNS • Paid escrow service out of country • Power generator system in main DC
