Earlier quoted context omitted.
Akamai makes you to set your own DNS server for it to pull records from, the domain getting hijacked should not have any effect on what that DNS server is returning.
I may be missing something, but this: >It added that its domain name system was compromised. sounds like their DNS server was compromised. Also, I've never worked with Akamai, but every cdn I have worked with just follows the ns records and resolves against that, which could be changed with access to the domain/registrar. Does Akamai not do that?
Not _their_ DNS servers getting compromised.
