Changes after the Dyn DNS Outage

Looking at NS records today some of yesterdays affected companies decided to change things after the DoS on Dyn. As the NS record is not really a customer facing feature this is more an indication of Dyn's customers expectations. One could argue switching away from Dyn could mean fear of more downtimes to come.

Here is a summary of changed NS records so far:
SiteBefore (15.10.)After (22.10.)
about.com dynect.net nsone.com
etsy.com dynect.net dynect.net
awsdns
github.com dynect.net awsdns
paypal.com dynect.net dynect.net
ultradns.org
paypal.com
xhamster.com dynect.net anycastns*.org
zendesk.com dynect.net ultradns.*
speedtest.net dynect.net awsdns
I did only check some NS records for changes, just several of the top sites. There are two note-worthy non-changers being Twitter and Github though, everyone else seems to have mitigated. Some to using two providers, several switching to AWS DNS or UltraDNS exclusively.
