    16. 16. What was the reason for contactingus?Importance of DNS• DNS is the ‘IP Address directory’ of the internet• Translates the domain/sub domain in every URLrequest to an IP Address• DNS is the critical ‘first step’ for your end customers toreach your site• If your DNS is unavailable, your site is unavailable• When your IP address changes, you need to updatethat DNS and propagate fast
    17. 17. What was the reason for contactingus?Why Dyn?• Evaluated DNS in lead up to a major data centremigration• Over 100 domains to move• Wanted a specialist DNS provider• Focus on Uptime / Speed / Propagation / Scale• Ability to load balance across data centresTIP : Note that doing DNS Load balancing candramatically increase the number of DNS querieswhich has a direct effect on costs so plan your needscarefully

    21. 21. What was the reason for contactingus?Move of existing DNS• Add the Dyn transfer IP to the ‘AXFR’ DNS attribute for all existing domains• Provide Dyn with list of a ‘Zones’ (domains) to import from your current DNSprovider(s)• Review all DNS resource records have imported correctly via the Dyn PortalTIP : At this point DO NOT make any further resource record changes until transfer isfully complete• Request each domains registrar to change the existing authoritative NS to Dyn NSTIP : Some TLD registries require written authorisation for NS changes so allow timefor this in your overall projectTIP : If you have a lot of domains to move do them in batches to make verificationsimpler• Check queries start to flow to Dyn (online statistics in Dyn Portal)
    22. 22. What was the reason for contactingus?Switch on new DC’s• Allow 7 days for any residual traffic (due to DNS caching) to disappearfrom the original Name Servers (NS)• Decommission original DNS provider(s) / NS• Prepare all resource record changes• Prepare any Dyn support needs• Use customer portal to make changes manually or script via api• VERIFYTIP – we were going from Active/Passive DC’s to Active/Active so we made ourchanges in two tranches. Firstly get up and running on one DC and then set upthe DNS load balancing to bring the second DC into play
    23. 23. What was the reason for contactingus?On-going Management• Use the customer portal for anyadhoc changes• Review your usage statsregularly• Use the Dyn team for help andadvice
    24. 24. What was the reason for contactingus?Future Steps• Automation• Dyn can automatically handleDC failover if yourarchitectural designaccommodates it• For our use case we needmanual control of failovers,but want to make the processhappen as fast as possible• Answer : Dyn REST API’s
