Is SBC-Yahoo DNS resolution slow?

I don't know if it's something on my end OR if there has been some kind of
change with the SBC-Yahoo DNS servers, but the past four days they have been
slow as hell resolving URLs.

I looked at dlsreports.com and didn't see anything but it's a limited audience
there and maybe there are more users here. I'm in the Sacramento, CA area.

Anyone else with SBC experience a 5 - 10 second latency when entering a new
(non-cached) URL?

If you are running Linux, it is easy enough to run your own caching
nameserver. I have been doing that since 1/2002, because when I first got
SBC adsl then, its DNS seemed sluggish (delay before web pages would start
loading, and trouble resolving some names). I still have occasional
problems resolving www.sbc.com, about the time I need to pay my e-bill.

Adding your own forward/reverse LAN zones can also make local connections
quicker when tcpwrappers or daemons want to resolve connecting IP.
Following the DNS HOWTO can also help you understand how DNS works. You
just have to occasionally remember to update your root hints file with
dig (if some names start failing). And it is probably best to set
listen-on and allow-query to only bind to or answer querys from loopback
and local IPs.

Do you know of a good (modern) tutorial to set up a caching nameserver in
Linux (I use Slackware.) Are we talking about bind? Or one of the other DNS
systems out there?

Thanks,
