This is becoming a FAQ. Here is the answer we sent to someone
privately, earlier this morning:

This is a fairly common problem. The problem affects sites hosted by
Akamai, including Apple, Yahoo, and others. The problem is not
specific to QuickDNS. Instead, it appears to be a combination of
factors, including using Mac OS X as the client platform - we suspect
there's some problem in lookupd. BIND 8 (the name server included
with both Mac OS X and QuickDNS for Mac OS X) may also be a common
factor, but we're not sure.

There is a separate problem with Safari that has been reported on
QuickDNS Talk. This parallel but apparently unrelated problem makes
it even harder for us to sort through the evidence that's been
presented to come up with a coherent theory of the problem.

Unfortunately, other than the three factors we've mentioned (ignoring
the separate Safari problem), we haven't found any other
commonalities, and there are plenty of counterexamples that contain
these factors. In other words, other people with very similar
configurations don't experience this.

The only workaround we can suggest is to simply try again. Whenever
an Apple, Yahoo, or other page fails to load, simply try again.
Usually, this works. One person has reported that he must try 3 or 4
times to get the Apple website to come up.
