I'm among several HN members who're experiencing an endless ReCAPTCHA loop when attempting to access Archive Today (<https://archive.today> a/k/a AT) or any of its various domain aliases:
All resolve to 23.137.248.133 for me.
This has been noted in comments: <https://news.ycombinator.com/item?id=37136514> <https://news.ycombinator.com/item?id=37132089> <https://news.ycombinator.com/item?id=37105936>
As well as an earlier HN story submission: <https://news.ycombinator.com/item?id=37077049>
As a practical upshot, as AT is the principle viable workaround for paywalled articles on HN, which means that HN is now left without a reliable option for such submissions. This becomes a policy issue for HN itself.
