Back in 2014, Wizards redesigned their website. A whole lot of links broke, but we figured out various archive URLs to still access the same content: How can I continue to access Wizards of the Coast's D&D 3.5 Web articles?
This method no longer seems to be working for accessing D&D 4e articles though — they might've been deleted, or migrated yet again without any redirection. There's still a D&D 3.5e article archive where some of the links even work, but I can't find an equivalent for D&D 4e, for example.
How can I access old D&D 4e articles, such as this one, which was once upon a time a wonderful article about its planes?
The Web Archive, which I'd usualy fall back on here, won't work for this page "due to robots.txt."
