Prepare for the 2017 IANA Annual Customer Survey. Commencing the week of 2017-10-23, our partner Ebiquity will invite our customers over the past year to participate in our annual survey. This anonymous survey helps us plan for the future by identifying our performance and ways we can improve. It will automatically be sent to those who have transacted requests with us in the past year, along with other key contacts within our community.
