It looks like their DNS record is missing, or their domain expired. I've tried looking it up using every tool I could find. This one actually lists DNS old registration values, from before the records were dropped. https://centralops.net/co/

Note below the Registrar Registration Expiration Date: 2026-05-15T13:51:43.222Z, that's about 4 hours ago.

Network Whois record

Don't have an IP address for which to get a record

Thanks for the report. We'll try to fix the problem as soon as possible, but no guarantees when that will be. For now, you can use alternative URL: https://rxjs-dev.firebaseapp.com

Nice; thanks. Hoping you get the domain re-registered before someone else takes it. Be sure you have "domain locking" enabled at your Registrar.

There are some pages down since yesterday, like https://rxjs.dev/operator-decision-tree.
Thanks for sharing the firebase url!!

The issue with DNS is now fixed, rxjs.dev is now online. We're sorry for inconvenience.
