[dns-operations] 2001:500:2d::d - d.root-servers.net behavior

[Kabindra Shrestha]

Hi Thomas,

We have shut the sessions for D-Root at Megaport Berlin and updated the
D-root team.

Also, not sure where you tried to contact PCH at but if you send us an
email at noc at pch.net, one of us would pick the ticket up.

Thank you.
