That is the same site as archive.ph with the same issue :/

Also they are known for abusing javascript on client browsers to DDoS someone they didn't like.

On Chrome, blocking javascript for each of these worked for me: [.]archive.fo [.]archive.is [.]archive.li [.]archive.md [.]archive.ph [.]archive.today [*.]archive.vn Also, see https://en.wikipedia.org/wiki/Wikipedia:Archive.today_guidan...?

Leaving aside for the moment the DDoS issue, that link is currently working for me. Archived pages on that site are puzzling, sometimes they work, sometimes they don't, I'm not sure what accounts for the difference.
