Is something out there bamboozling Squid?

[Brett Glass <squid-users@xxxxxxxxxxxxxx>]

Everyone:

Just this past week, our Squid cache has become balky, with long 
page loads from some sites and timeouts or partial page loads from 
others. (It's gotten to the point where performance is better 
without the cache.) I thought that it was just us, but another 
system administrator in town has complained of the same symptom: 
weird delays through the cache and none without it.

Is there some popular site out there which has started doing 
something that ties Squid in knots?
