I can confirm I'm seeing "flakiness" with those IPs from my Linux boxes 
co-located @ FRII. I tried from different boxes which are on different 
subnets, each with their own ethernet drop (e.g. two drops).

Sometimes it wouldn't connect, sometimes it would connect but a "GET /" 
would return nothing, and sometimes a "GET /" would show IIS ebay crap:
Server: Microsoft-IIS/5.0
Date: Tue, 27 Dec 2005 22:04:34 GMT
Server: WebSphere Application Server/4.0

I then tested from two OpenBSD boxes at the FRII co-lo. They were able 
to connect /every/ time.

So? Linux kernel bug?

Hmm. I then tested from my Linux laptop connected here in argentina to a 
  cable modem.  It could connect 100% of the time.

The Linux boxes that failed above were running kernels, um, 2.4.30, 
2.6.10 & 2.6.12.

Perhaps it's this: the akamai or akamaiish boxes that are caching for 
ebay that are between FRII & eBay have some incompatability with the 
Linux kernel.
