[CentOS] nscd

Has anyone had problems accessing random websites since going up to 6.4?

Since about the day after I got partly upgraded, if I try to access
nytimes.com, or orbitz.com, I get server not found.

With a lot of work, I, my manager, and the other admin, found that setting
options edns0 in /etc/resolv.conf fixed it - I suspect that the network
folks updated their internal nameservers (which are M$) about that time...
but... we got this Thurs. Friday, I went to look, lunchtime, at a story,
and back to the same. Later, and I think I was playing around, it came
back.

Just now, over lunch, it failed... until I restarted nscd. My manager
tells me it's caching... but it seems to be caching momentary failures.

So: has anyone else seen oddness that might be related to nscd?
