[outages] DNS resolution of ebay.com

[Frank Bulk - iName.com]

We've received two calls complaining about access to www.ebay.com.  Further
checking shows that none of our DNS servers can resolve either www.ebay.com
or ebay.com.  DIG returns a "timed out".  Flushing our caches made no
difference, and our upstream provider's DNS servers are acting the same way.

Digging against 8.8.8.8 works fine, but against the 4 NS servers listed for
ebay, they don't, probably because their DNS server is all ebaydns.com.
