This may be of interest to anyone who received complaints of slowness to
the Netscape home page yesterday.

Yesterday, Jeff Halper asked this on our squid-users list:

The problem turned out to be sort of interesting, so I thought I'd share
it with you...

First I thought I'd see if Jeff was imagining things or if there really
was a difference.  So I looked at the "service time" value for
* requests from four days of access logs.  The results

		Median Service
	Date	Time (seconds)
	-----	--------------
	Jan 3	 2.47
	Jan 4	 3.47
	Jan 5	 5.81
	Jan 6	76.17

So obviously, something was seriously wrong.  The next thing to try was
a simple ping:

	sv-wessels> ping
	PING ( 56 data bytes
	64 bytes from icmp_seq=5 ttl=248 time=603 ms
	64 bytes from icmp_seq=6 ttl=248 time=550 ms

Say what?  WWW-UK2?

sv.cache, located at FIX-West, uses for DNS service.
Every time I checked the rest of that day, always
returned, even though the DNS TTL was quite low
(less 15 minutes).

Looks to me like some DNS smart-resolution feature gone haywire.  I
sent mail to dns-admin at, but have yet to get a reply.
Since it seemed that was not going to "fix itself" any
time soon, I changed sv's resolv.conf to use a different DNS server
temporarily.  Today, is giving us good answers
(  Shrug.
