[outages] Two of www.ebay.com's six IPs timing out on HTTPv4 request

[Frank Bulk]

Our monitoring system reported errors with HTTPv4 requests around 11 pm
Central.  

www.ebay.com has six IPs for me:

C:\bin>dig A www.ebay.com +short
www.g.ebay.com.
66.135.200.181
66.135.210.61
66.135.210.181
66.211.181.161
66.211.181.181
66.135.200.161

Testing showed that queries to the other four work well, but 66.135.200.181
and 66.211.181.181 time out for me.

I used NAGIOS' check_http and httping to check, as I can specify the target
IP and it queries the whole page, not just the head.  Anyone else seeing
this?
