keenspace.com, a free hosting service for comic strips, changed its name (not long after it was founded) to comicgenesis.com; but the old name still works, as do comicgen.com and (I just learned) toonspace.com and webcomicspace.com. Well, mostly.
Mostly it doesn’t matter whether you look at foo.comicgenesis.com, foo.keenspace.com or foo.comicgen.com; you get the same content. But sometimes images don’t show unless the address is foo.comicgenesis.com.
What’s going on here? Apparently these domains are not transparent synonyms for each other; but why would they be (flawed) mirrors?
