==LacusCurtius==
I'm sorry you're having trouble with the LacusCurtius site, but the links we have don't meet the definition of "dead links": see WP:Link rot. These are still the correct links; the site hasn't ceased to exist or changed its address; and people can still reach the site through these links. There's no such thing as a link that's dead to some users and not others. The page loads slower for me than any other site I use regularly, so whatever causes that may be the source of your difficulty as well. But the page is located at the given address, and the link is still active, so it isn't a "dead link".
