For the last month or so archive.is is not working for me, is it maybe related to this? Btw I always assumed owner is from Russia because he or they were so secretive about everything except occasional blog post or occasional Q&A and Russians are usually obsessed by their web pet projects.

For real someone needs to make legit business of archiving the web where you would have timestamped hashes of your archived web pages and "unlimited" storage for archiving ofc only if you pay for the "unlimited" storage.
