Is Daily down?

We're seeing a recurrence of the problems with RegistryDNS.co and AT&T DNS from Monday. Users trying to join calls from affected regions using ISP DNS may get "Unable to join call" errors. We know specifically that AT&T DNS servers 68.94.157.1 and 68.94.156.1 are affected. We've been working hard on solving this problem since the incident on Monday. We're releasing daily-js 0.91.0 shortly to address this.

We expect to have daily-js 0.91.0 available within the next 60 to 90 minutes. The update includes automated failover to `dailywebrtc.com` or `dailywebrtc.net` if `daily.co` is unreachable. If you haven't updated daily-js in a while, you can do preliminary testing with 0.90.0 in order to be ready to release an update with 0.91 as soon as it's ready. 0.91 will only contain this feature, as well as a few dependency version updates for security. If you have customers with restrictive networks, they may need to add `*.dailywebrtc.com` and `*.dailywebrtc.net` to their firewall/security allowlists. These domains are relatively new, so they may be flagged by Cisco app firewalls and similar security appliances.

daily-js 0.91.0 is now available on npm and GitHub. If your app uses call object mode, you can update your dependency to that version and redeploy, and this issue should be resolved for you. We're publishing an update to our networking guide soon, but in the meantime, anything that mentions a `.daily.co` hostname in that doc is also available at `.dailywebrtc.com` and `.dailywebrtc.net`. We'll have updates for embedded Prebuilt and direct link customers soon. We'll leave this incident open while RegistryDNS.co remains offline.

The RegistryDNS.co servers continue to be intermittently unavailable, but AT&T's DNS servers seem to be more responsive. We encourage you to update to daily-js 0.91.0 as soon as possible to avoid future issues for your users.

We've identified an issue that's preventing some users from being able to join calls, resulting in errors like "Unable to join call" in the browser. This is being caused by failures from the DNS servers that serve the .co TLD itself. Several third-party DNS providers like Google, Cloudflare, and Quad9 are working around this in order to continue to make .co domains available. But users that are using their ISP's DNS service (specifically AT&T users in the southeast US and/or Texas) are experiencing intermittent problems accessing any .co domain, including daily.co. Unfortunately, the only workaround is to encourage your users to use a third-party DNS provider, like Cloudflare or Quad9. We're working on addressing this long-term.

We are working on implementing a fallback to a .com domain so that users on ISPs that are not fixing this will not see any issues starting calls.

CentralNIC confirmed that there was indeed an issue with the .co nameservers, and they resolved it at approximately 06:30 UTC today. Our monitoring of both their DNS servers and downstream providers confirmed this. We're continuing to work urgently on updating our infrastructure to make our services available on alternate hostnames. We'll post updates to our Networking Guide when we do: https://docs.daily.co/guides/privacy-and-security/corporate-firewalls-nats-allowed-ip-list We'll also provide a root cause analysis for this incident in the next few days.
