godaddy ipv6 nameservers are not reachable

[Matjaž Straus Istenič]

Dear Janos,

we (AS2107) have experienced same problems on the route with AS_PATH 20965/GEANT 6939/HE 209/Qwest 26496/GoDaddy. If we send traffic directly via Level3 (AS_PATH 3356/Level3 26496/GoDaddy or even 20965/GEANT 3356/Level3 26496/GoDaddy) it works fine. Hope this information will be valuable to you.

Kind regards,
	Matjaž
