Noting this as I can see that this happened in June and I suspect the DNSSEC keys have been updated incorrectly again. The connectivity checker stopped working for me at around 1:30 GMT/UTC today. I use my home AdGuard installation as a private DNS server and that was having problems resolving the domain, as is Quad9 and Mullvad DNS. Cloudflare and Google are currently working.
