Dismissing it as a "bug" in "my" infrastructure is just plain wrong. It
has nothing to do with "my" infrastructure. 30 percent or more of the
sites on the Internet are affected by this problem. This is a severe
bug. There is nothing I can do to change the infrastructure sitting
around the world between me and the 30 percent of the sites where this
problem manifests consistently. If you want to track down all the
colo/networking facilities around the globe through which this "bug"
manifests. In the meantime, I cannot access sites like Slashdot and
hundreds of others and this has nothing to do with any network I'm on
(the problem is identical on the two totally different consumer broadband
networks in Silicon Valley which I used).
