Re: [outages] Ebay dns record

None of our ISPs' DNS servers can reach ebay. Expanding on that list, it appears that the only DNS servers able to dig ebay are the ones that cache. Is anyone else seeing this?

This is not what I see:
Hmmm. Let me phrase it differently: When I dig +trace, I do not expect GDNS to be the first hop, and the end records to be the second. I'm not sure what is causing that, but I'm relatively sure it's something doubleplus ungood. See the two traces in my original posting, if it's not clear what I'm complaining about.
