As we have working IPv6 again, I've also added murasoi's IPv6 address: 
http://www.pool.ntp.org/scores/2405:3c00:5200:100::1

At 10Mbps, over about 5 days, there were about 1.9bn requests, which works 
out to be north of 4000 requests per second. I've since increased the 
netspeed to 100Mbps, however traffic levels will be dropping as iOS users 
update Snapchat (which was the source of the traffic) to a version that 
doesn't poll NTP servers around the world. More details are at 
https://community.ntppool.org/t/recent-ntp-pool-traffic-increase/18

The servers are currently managed under my work account, but it's pretty 
set and forget, all you can do is set the netspeed or delete them. Worst 
case if they need to be transferred to an account with a UCC email address 
is I can delete them then they can be added to the new account.
