[dns-operations] Contact at Akamai

[Dave Lawrence]

I anticipate that Ralf Weber will be chiming in, but if your issue is
that Akamai authorities don't seem to be giving you ECS-mapped answers
despite a valid ECS option, this is expected if you don't have an
agreement with them.

Akamai doesn't (or at least didn't, for a long time) allow ECS options
from anyone.  Per this article:

There is a link at the bottom for ECS Onboarding with Akamai, login
required.
